Call to undefined function get_network_option() - wordpress

I have a WordPress blog that I admittedly haven't been looking after/not upgrading the plug-ins etc I'm regularly emailed about - and now it's down.
No matter what page I go to, I get:
Fatal error: Call to undefined function get_network_option() in /home/gfptlkxn/public_html/blog/wp-content/plugins/wordfence/lib/wordfenceClass.php on line 747
I've done a bit of googling on this and it seems a common problem, but more for people making changes/trying to use certain features etc - I've not changed anything/not doing anything fancy - it's just a simple blog.
So I figured maybe I could just go into my login page for WordPress, have a dig around, upgrade some plugins etc as a starting point.
Problem is, even my login page presents this error.
Any ideas where to start please?

There may be a compatibility issue between the WordFence plugin and your version of WordPress (as noted in the WordFence forums).
You should log into your website using FTP and delete the directory: /home/gfptlkxn/public_html/blog/wp-content/plugins/wordfence/
If you do not know or have FTP/SFTP access to your site, you may be able to log into your web hosting cPanel (or equivalent) and remove the directory using the File Manager feature.
Once that directory has been deleted, WordPress will be able to load again (and will automatically disable the no longer present WordFence plugin).
Once you've managed to log into WP-Admin, upgrade WordPress to the latest version, the install the WordFence plugin again if you need to.

Unable to access wordpress page after update

I'm facing an error with wordpress. I updated wordpress page by mistake and I'm getting error
The site is experiencing technical difficulties. Please check your
site admin email inbox for instructions.
When I try to access the page by admin. I can't revert the change since the unable to access the page from admin. Is there any way to fix this issue.
Kindly clarify your question, you updated one of the pages in your WordPress site or did you update WordPress to the latest version and got an error afterwards when trying to log in within the admin dashboard?
If it is a page you can't access, try disabling your plugins and see if it will be accessible. You can also try to enable WP_Debug to true from within the wp-config.php within your back-end file manager and see if the exact issue will be displayed so as to assist you with further troubleshooting.
Alternatively, if the issue arising is due to a WordPress update to the latest version, you can try renaming the plugins folder temporary from within your backend as a form of troubleshooting, if that fails, temporary rename your theme (/wp-content/themes/theme_name) to try and pinpoint the exact issue. All this can be done with the WordPress folder from cPanel, file manager.
If the above fails, go a step further and try doing stuff like PHP memory increase, post_max_size &c.
If all the above fails, refer to WordPress documentation on how to do a manual WordPress update and hopefully, the issue will be fixed.
Note: The above is just an insight of what you can look into and not a step by step guide to fixing the issue.

Wordpress Dashboard broken, displays “flashbacks” of comments/plugins/updates

I’m using the latest version of Wordpress (4.7.4).
I have something very weird going on in my Dashboard. Not sure when this started.
Can’t say for sure it started with the latest version of Wordpress or not.
My Dashboard became completely useless.
It’s like it’s showing me a flashback of a Dashboard from a few days or hours ago:
Comments I’ve deleted in the Dashboard (hitting “trash”) are suddenly back there, awaiting my moderation.
Plugins I’ve deactivated or even deleted are all back there and according to Dashboard still running (while in my FTP folder they’re certainly gone).
The plugin page cannot be trusted anymore as it shows some plugins are activated that aren’t and vice versa. I have to check on my actual website to confirm which ones are running.
Updates aren’t shown correctly. Once I’ve updated a plugin, a few minutes later it shows me again that there’s a new update.
As you can tell it’s all pretty much the same phenomenon.
It’s as if I’m seeing an older version of my Dashboard.
Not sure what else is broken.
The only other thing I noticed is that even on my actual blog I still see a comment. Blog post says “1 comment”, but the actual comment doesn’t show up.
At first, this all sounds like a “cache problem”.
But I’ve already turned off all caching:
No caching plugin installed
Turned off server caching via htaccess
Disabled leverage browser caching
Emptied my own browser cache
Other things I tested:
Turn off all plugins.
Switch to the standard Wordpress theme “Twenty Twelve”
I tried WP_DEBUG, but nothing related shows up.
I researched the internet, but nobody has described a similar problem, so I suppose this is not a common Wordpress issue.
The issue remains.
Unfortunately I’m not a developer and don’t know too much about the Wordpress codex etc.
But to me it sounds that the mistake is definitely not in the plugin or theme folder.
The problem is that I’ve reached the point where I really cannot turn off plugins via Dashboard properly anymore. It’s so annyoing!
My questions are:
Is it safe to assume that this is related to the Wordpress core
files?
What files exactly are in “charge of” the Dashboard?
Should I just try to re-download the newest Wordpress version and replace a few files (if so which ones)?
Should I do a clean Wordpress re-install or would that be too drastic?
Any other suggestions?
EDIT:
Additionally I tried now:
I manually downloaded the newest version of Wordpress and did just as
described on the Wordpress.org website. I manually replaced wp-admin,
wp-include folders and all root files. The issue remains...
The way my Dashboard is right now, I really can’t use it.
Please advice!
I contacted my host service again.
They just gave me the same line to insert into my .htaccess file and I told them I already tried it and it didn't work.
I then showed them my .htaccess file and they deleted the whole part that concerned their server caching.
Now server caching is completely off and everything works again.
Still not sure why this previously never caused issues.
In the end, it had nothing to do with Wordpress.
I hope this answer will help people who run into similar problems.

Can't access Wordpress admin login page (redirect error)

I’m working on a wordpress site, it’s almost finished.
Left it lying on the server for a few weeks after the launch to gather user feedback, and now ready to make some minute adjustments.
Loe and behold, can’t login.
Going to parentsauxassembleesgenerales.org/wp-admin won’t show me the admin page, but will instead redirect.
Sure enough, I had an automatic update to 3.8.2 on April 9 that seems to coincide with the admin access being gone.
Contrary to most redirect errors for login pages after an automatic update on forums, the exact url it redirects to is not actually a valid url.
You see others reporting the url they are redirected to as being:
http://www.domain.org/wp-login.php/?redirect_to=http%3A%2F%2Fwww.domain.org%2Fwp-admin%2F&reauth=1
But mine displays: http://www.parentsauxassembleesgenerales.org-login.php/?redirect_to=http%3A%2F%2Fwww.parentsauxassembleesgenerales.org%2Fwp-admin%2F&reauth=1
And is therefore missing three characters: “/wp” to be identical to the other bugs I saw reported. Needless to say, I still tried all the fixes recommended elsewhere, namely:
(using FTP, Softaculous, dowload of WP 3.8.1 and 3.8.2 from wordpress.org, and PHPmyAdmin)
1- deactivating, renaming, removing plugins, theme, both plugins and theme
2- adding lines of code to wp-config
3- looking at the database to make sure the site url and home url were the right ones and the same
4- updating key files like wp-login.php with a fresh version straight out of a vanilla install.
5- moving the content and wp-config to a fresh install (only recreated the problem).
I’m sort of confused at Softaculous (wp install script in cPanel) for asking if you want automatic updates, but still enabling the small automatic updates (3.8.1 to 3.8.2 or 3.8.3) even if you don’t check the box for automatic updates. I don’t, and never will, want automatic updates on my wordpress: too many plugins and themes have a lag to the wordpress core deployment schedule. (I now know I can just add a line to wp-config.php, but the Softaculous interface could be clearer about the automatic update deal).
Am now in contact with the hosting service to look at solutions such as emptying webcache, restoring from their own weekly backups, their own diagnosis of the faulty redirect route, etc.
I’m looking for a solution that will do one of the following:
help me know what causes the redirect error so I can target the problem-solving
help me regain access to wp-admin login and the dashboard
I found the issue.
Despite deactivating the plugins, one of the plugins had caused a problem in the DB which remained even when deactivated, removed or renamed. Had to clean up the relevant redirects in the DB with PhpMyAdmin.
The plugin was Velvet Blues Update URLs, which was recommended for a very small move I was doing (moving the dev version of the site up one folder on the server file system).
I hadn't used this plugin before, but it seemed straightforward enough.
Not.
I usually migrate sites using UpDraftPlus with the pro addon for migration, which works fairly well, but felt longer than it needed to be for a one-folder-up move.
Not.
The search and replace feature on UpDraftPlus that covers both for file/folder locations and for urls is without compare, and even for what it was supposed to do, Velvet Blues Update URLs didn't deliver on its promise.

Posts disappearing and reappearing on wordpress

I have a wordpress site which is acting strange lately. It seems like the database is spontaneously rolling back a few hours from time to time. I have noticed it happen at least four times.
When I updated to wordpress 3.5, after a short time, maybe 30-60 minutes I noticed the nag to upgrade was back. I ran the upgrade a second time, even though I was certain that I had already upgraded.
I added a new category and changed a widget on one of my sidebars, only to find that my changes were gone the next day and I had to redo them.
I added a post yesterday, linked to it in various places and then returned several hours later to find the post missing. I rewrote the post from memory and put it back on the site.
This morning when I went to the site, the original post was back and the one that I had recreated from memory was gone. The post's id number was the same as the previous day. I think there was also a draft post that disappeared and reappeared as well.
One last clue which may or may not be related is that when I go to a page on the blog that should generate a 404 message I get a single piece of text which says: "defaced by t3ll0" I noticed this recently, within the last few weeks. I'm not sure how long it has been like that.
I ran Sucuri Scanner, and it found no evidence of malware. Any suggestions of how to troubleshoot this? Could this be a problem with my database rather than wordpress?
UPDATE: It appears that the primary problem I was noticing was because of two versions of the site being up simultaneously. The DNS settings had not been updated to the new site. I'm still investigating if the site was hacked.
You got hacked. "defaced by t3ll0" is the clue. Someone has control of your site and your hosting account.
Work your way through these resources and follow all instructions to completely clean your site or you may be hacked again. See FAQ: My site was hacked « WordPress Codex and How to completely clean your hacked wordpress installation and How to find a backdoor in a hacked WordPress and Hardening WordPress « WordPress Codex.
Change all passwords. Scan your own PC for spyware that may have grabbed your login and password.
http://sitecheck.sucuri.net/ is a good resource, but it scans for malware and not accounts that were hacked and are not being used to distribute malware or have spam links.
Tell your web host you got hacked; and consider changing to a more secure host: Recommended WordPress Web Hosting
You have not applied security may be at number of places.
1. File permissions, folder permissions.
2. Upload folder permissions.
3. Execute permissions.
Now, if you are not a developer how would you check for these vulnerabilities?
I am suggesting you to take a backup of your DB(Export it). Get rid of the existing WP core and reinstall it from fresh.
Delete all plugins and install them all from fresh sources.
If you have used a custom theme then get the backed up version of it and delete the current one as there is a deface to it.
And you can check for a lot of vulnerabilities with plugins like this: http://wordpress.org/extend/plugins/better-wp-security/
Rename your administrator account. Harden your password. Remove write permission from .htaccess and wp-config.php file.

How to resolve a bad plugin server 500 error wordpress

I was just working on a Wordpress site and after updating a plug-in (which had not yet been activated, only installed) I activated it. Instead of the activation working, it gave me this error:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete >your request.
Please contact the server administrator, webmaster#ibsmithmedia.com and inform them of >the time the error occurred, and anything you might have done that may have caused the >error.
More information about this error may be available in the server error log.
Additionally, a 500 Internal Server Error error was encountered while trying to use an >ErrorDocument to handle the request.
I am getting this error on every page of my wordpress site, not just the plugin page or my user admin area.
How can I fix this? Is there a way to undo this plugin activation (I'm pretty sure it's what's causing the issue).
I don't have access to the actual FTP files of the site, I'm working on it for a friend. But I can get access if that's the only way to fix this. Thanks!
I would get access and delete the plugin.
That would be the fastest solution.
I ended up having to delete the folder for the plugin and then going to my htaccess file and remove extra lines that the plugin had added there as well. That resolved the issue.
First you need to connect to your website using FTP client, or File Manager in cPanel. Once connected, you need to navigate to the /wp-content/ folder.
Inside wp-content folder, you will see a folder called plugins. This is where WordPress stores all plugins installed on your website.
Right click on the plugins folder and select Rename. Change the name of the plugins folder to anything that you like. In our example, we will call it “plugins.deactivate”. Once you do this, all of your plugins will be deactivated.
Usually, this method is used when you are locked out of your admin area. If the issue was with your plugins, then you should be able login to your WordPress admin area.
Once you do that, go back to your /wp-content/ folder and rename “plugins.deactivate” back to plugins.
Now you can activate one plugin at a time until your site breaks again. At which point, you will know exactly which plugin caused the issue.
