 * This plugin is completely different with PHP8 that will be deployed (I currently
   run PHP 7.4): no tree at left with the folders and a toggle remove this column
   that remains blank (and is useless) to have in the above line a cell in the menu
   for the listing of the folders and then you can select a folder and get only 
   the pages of this folders . I prefer the tree
 * Regards
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fthis-plugin-with-php8%2Fpage%2F2%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * This issue has been resolved and was being caused by the following PHP fatal 
   error:
 *     ```wp-block-code
       Uncaught Error: array_filter(): Argument #1 ($array) must be of type array, null given; line 479 in wp-includes/class-wp-user-query.php
       ```
   
 * This was the result of a corrupt user role (the role’s capabilities property 
   was null instead of an array). Resolved by re-saving each role’s capabilities
   using the PublishPress Capabilities plugin.

   the log file but I did not know what to do and gave the information to Elegant
   Theme (the theme divi)I have a questionYou fixed the issue in the site: [https://new.choeurpolycantus.fr](https://new.choeurpolycantus.fr),
   that is a test siteThe production site is [https://choeurpolycantus.fr](https://choeurpolycantus.fr)
   I must check if the issue exists also with the production siteIf it exists in
   the production test, can I fix it and what is the way for me to have this issue
