Classic Editor and PHP 8

But with classic Editor, when I want to create or modify, I have a fatal error :

It is in the core file “class-wp-user-query.php” at line 479; and the tab “view” is empty; only the tab “text” is ful filled. But it runs with Gutenberg.

Hi @mars29dr your debug log is showing fatal errors for the Classic Editor and warnings for the Gutenberg plugin. Is that the case?

This may be a plugin or theme conflict. Please attempt to disable all other plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your problems

Any composer with php 8+ I get the following error:

uncaught Error: array_filter(): Argument #1 ($array) must be of type array, null given
wp-includes/class-wp-user-query.php:479

I have no idea why?

My fatal error is corrected and classic editor runs now with POHP 8.1. There are always warning and “deprecated”. The problem is that I have roles in my members. Somme roles were corrupted. I have to delete them and rebuild them and I use the plugin . Below the process that I was given by a developer of the plugin Wicked folders, and I thank him very much for his help.

1. Install and activate PublishPress Capabilities plugin
2. In your WordPress admin, go to Capabilities > Capabilities
3. In the roles dropdown near the upper-left area of the screen, select the first role
4. Click the Save Changes button
5. Repeat this for all roles (i.e. select a role and then click Save Changes)
6. Once you’ve saved all roles, you can deactivate the PublishPress Capabilities plugin

@quiethero1 – could you please start your own thread, as your issue is not the same. Thanks!

@mars29dr – glad you got to the bottom of the problem. Thanks for providing the solution in case it helps anyone else in the future. I’m marking this as resolved.

The response I gave is available in my context of the use of roles. In other contexts, I do not know
