I can't Edit/Add New Post in Wordpress - wordpress

I've tried everything:
Deactivate plugins and reactivate one by one
Configure .htaccess
Change Permalink
Re-install Wordpress
The issue is in the theme I guess. Whenever I changed mine to default, it works, but not with the current one.
I am using Averie Theme: screen shot

Problem Solved! The issue is in the theme. I just upgraded the theme to latest version

Try to change the theme to like Twenty seventeen etc.. and see if the issue is still remains. as Jovan Jovanović said, it can be related to your theme.

Classic editor, incomplete at that, after WordPress 5.9.3 update. For Posts only it seems

I cannot edit my posts after an update to WordPress 5.9.3. They show up in classic editor format with no visual/text editor section. The same is not happening with my Pages though (they appear in block editor). I am using the blocksy theme but the issue does not go away with the Twenty Twenty-Two theme as well. Just to clarify, I want the block editor.
Make a backup.
Deactivate all plugins and test if it works. Change the theme and test if it works.

Elementor header and footer disappear after activating WPML plugin

everyone.
I installed and activated WPML plugin for multi-language.
But after activating it, my elementor header and footer disappeard.
I tried to find the solution.
The blogs say that it is due to compatibility issue.
So I should remove all plugins and install one by one.
Can't I fix this issue without removing plugins?
The original question was year ago, but for the other people faced the issue:
You can try to re-save the conditions for the Header and Footer in the Elementor Theme Builder section, it should resolve the issue.
Also there's the similar (currently, opened) issue on the Github which may help: https://github.com/elementor/elementor/issues/15306
They suggest to change the plugin's code:
https://wpml.org/errata/elementor-pro-template-display-conditions-does-not-work-with-multiple-languages/
Please be awared, changing plugin's code is a terrible practice, but it's just a one line of code which could prevent the issue, at least before the plugin's update.

Polylang issue after install

I've installed Polylang to a new WordPress website. I've added the default language but then every page is white. What can I do to solve that?
The permalinks is: postname.
I've tried to change the settings of the plugin or something else but it's not working.
Apperantly, this can happen when the theme cannot differentiate between Polylang and WPML and then tries to make use of WPML specific functions.
More information about this can be found here.
And the solution is to add the following line inside wp-config.php:
define('PLL_WPML_COMPAT', false);

WordPress: fresh install: Twenty Twelve theme does not display images

Here is how I installed WordPress. I installed xampp in C:\xampp
and started apache and mysql, created the wordpresstest database,
extracted wordpress-3.5.1.zip to C:\xamppp\htdocs\wordpresstest
and did an http:// localhost/wordpresstest and proceeded with
the installation (I did this twice because I wanted the
root directory to have a different name, so I deleted
the database and recreated it and deleted my
wordpress folders and reextracted them and
reinstalled).
The problem I am having is that the Twenty Tweleve theme is
not displaying any images:
whereas the Twenty Eleven theme (the only other theme that
came with wordpress) seems to be working fine:
Can someone please explain to me why the default install theme
(Twenty Twelve) is not working as expected? Basically it does
not seem to be able to use the right style information.
Thanks.
In spite of what appears in the theme screenshot, Twenty Twelve doesn't seem to have a default header image.
Go to Appearance -> Header and try to upload a header image.
Twenty twele doesnt have a default header image.If you want add a image to header you can add it from Appearance. The two default themes have different themes. There is no any issue with your installation or Wordpress. This is how it comes and you have to select any theme that is suitable for your preference and customize it.

Wordpress theme not displaying (after updating to 3.1.3)

I'm building a custom Wordpress theme that was working but at some point the theme stopped loading in Wordpress and Wordpress switched back to the default TwentyTen.
I think it may have had to do with upgrading to 3.1.3. Any pointers on how to debug this?
Turn on WP_DEBUG in config file
http://codex.wordpress.org/Editing_wp-config.php
Aslo except for WP_DEBUG when themes are not showing up and just displays blank pages there is usually a quick fix:
Change to another theme in the admin panel
Change back to the theme that was not working
If the theme has a hyphen in the name, remove it.
Check so that all the files are in their proper place
Check so that all the files are named right
When the theme doesn't have a screenshot it's hard to spot, even though it's in the list. Check again carefully.
