I'am getting the message "Can not send a message to the site to verify the absence of fatal errors. As a result, the PHP modification has been canceled. You will need to upload your modified PHP file by other means, for example using an FTP client." when i try to update files on the wordpress editor, i've noticed this error after the last wordpress update.
Thanks,

The form is created using Contact Form 7, but the submit action is made with AJAX and a file php which made a database conection, the error return: 500 (Internal Server Error) on php file and: Uncaught TypeError: $(...).AjaxDebug is not a function on AJAX function.
In the debug file generated by WP there is nothing related with this error.
someone can help me to understand this problem?
I disabled the plugins one by one, hoping for the problem is a conflict, but nothing change.
you clean the cache?! use a plugin like Super Cache good luck
I get this error when i want to add a featured image to my wordpress post
"Updating failed. Error message: The response is not a valid JSON response."
In my case it was due to a web server configuration (Apache2):
AllowOverride None
Changed it to :
AllowOverride All
in
/etc/apache2/apache2.conf
I had the same "not a valid JSON response" error when trying to publish my content. WordPress seems to do a JSON post when publishing a new post/page so I checked the network tab in my Developer Tools. If you check the "response" tab for this JSON call you might see some more details about this invalid JSON response.
In my case (yours might be different) some deprecated debug message was outputted before the actual JSON data and messed up the response. After fixing the deprecated message publishing worked again.
If you are trying this on your local or production wordpress install you may likely get this error as your .htaccess file is not writeable for security reasons.
Error you will see in wordpress admin interface under permalink setting after you change from plain to any mode:
If your .htaccess file was writable, we could do this automatically, but it isn’t so these are the mod_rewrite rules you should have in your .htaccess file. Click in the field and press CTRL + a to select all.
Make sure your .htaccess file is writeable whenever you change your permalink setting from PLAIN mode to anyother mode like POST-NAME
For me this error was shown in the backend editor because of a line of text in another file which echoed that line of text on each response. Incl. when WordPress internally made its own request expecting a JSON response. Once i removed that line issue disappeared.
I got the same error:
Updating failed. Error message: The response is not a valid JSON
response
after deactivating WordPress plugin Gutenberg. I tried to reactivate it but the error still exists.
The solution to my error was installing the "Classic Editor" plugin.
I am trying to move my WordPress site from one hosting service to another. I made a backup and restored it on the new host. But I am getting internal server 500 error on the site. I have tried to fix the .htaccess file but its still giving error.
The issue is, if I try to rename it to test it, its not giving the internal 500 error but redirecting me to WordPress installation page called wp-admin/install.php
Can someone help me for solve the issue.Thanks
All the suggestions that are given are great, but if those do not work, then you can try to downgrade PHP. It had worked in my case when I was facing the same error.
You can dig in the error log and find what exactly is causing the error.
Steps for debug.
As previously said: stop all plugins and try again. If problem still exists check logs again. Then switch to default theme and so on.
Btw have moved the DB properly? With the same connection settings.
I think you should check your wp-config.php and PHP version. make sure you have entered correct DB info in wp-config like db_name, password, and table_prefix etc...
if You have changed hosting, probable You need to check database and .htacess file. If You are getting installation page means its database issue, Please check database prefix in wp-config.php file and it will solve your issue.
there are lot of causes for internal server error. The main reasons for internal server errors are.
Corrupt .htaccess file
PHP Memory limit
Faulty code in Theme
Corrupted plugin
Corrupted core files
Incompatible PHP version
In oder to fix this issue, you need to investigate in step by step order.
To solve this issue first of all you need to enable Debug mode and check the issue.
after that try with restoring .htacess file, enabling default theme, disabling plugins etc.
if you still facing 500 internal server issue, follow tutorial on WPERA to fix 500 internal server error. Hope this helps.
I am re-designing someone's Wordpress website and moslty need to change the CSS I wanted to move the entire website over to my server in order to develop it. Mostly I am just changing the design/CSS but there are some custom parts I want to keep such as there is a testimonial plug-in/widget that has a custom place in the dashboard and a way to post testimonials.
I downloaded the entire site.
Exported the database
And then moved it to my server and uploaded the files and created a new database and imported it.
Then I used this to change the database to the correct directory:
https://interconnectit.com/products/search-and-replace-for-wordpress-databases/
Now I am getting a crazy error:
Warning: Cannot modify header information - headers already sent by (output started at /home//public_html/wordpress/wp-config.php:156) in /home/public_html/wordpress/wp-content/plugins/wp-greet-box/includes/wp-greet-box.class.php on line 493
Warning: Cannot modify header information - headers already sent by (output started at /home/llhimhi1/public_html/wordpress/wp-config.php:156) in /home/l/public_html/a/wordpress/wp-includes/pluggable.php on line 1121
I don't know if I should continue trying to make this work, or just copy the theme to a fresh install. But I am not sure what else to copy since there are custom plugins and stuff in the dashboard.
Help would be much appreciated.
A "headers already sent" error is a very common PHP error having to do with white space or junk characters in a file, or a file that was corrupted during FTP transfer. Check your wp-config.php file.
From FAQ Troubleshooting » Headers already sent warning « WordPress Codex
It is usually because there are spaces, new lines, or other stuff
before an opening tag, typically in
wp-config.php. This could be true about some other file too, so please
check the error message, as it will list the specific file name where
the error occurred (see "Interpreting the Error Message" below).
Replacing the faulty file with one from your most recent backup or one
from a fresh WordPress download is your best bet, but if neither of
those are an option, please follow the steps (at the link above).
And read http://codex.wordpress.org/Debugging_in_WordPress on how to set up debugging to find causes of "white pages" and other PHP errors.
Hey All,
I'm a bit new to the WordPress game, and was trying to set up my server with WordPress. I was running through the installation, and just entered the host, db name, and pass, and hit go, when I see this:
Fatal error: Call to undefined function is_admin() in /var/www/WordPress/wp-admin/includes/comment.php on line 162
I've got no idea what this error means, though a google search turned up several websites with the same error; for example:
Site
All help appreciated!
Reupload fresh copies of all Wordpress files and folders, except for wp-config.php. Some of them didn't fully upload the first time.
