 * After the update to WordPress 5.9. the editor no longer works and the following
   error message indicates that your plug-in is the reason.
 *     ```
       TypeError: Cannot read properties of undefined (reading 'className')

 * If I switch it off, the editor works again.
    Looking forward to an update.

 * I solved this temporarily by editing block-options/extendify-sdk/app/Admin.php
 * Added a “return false;” in the last function
 *     ```

       //DISABLE EXTENDIFY TEMPORARILY
               return false;
   
               // If it's disabled, only show it for admins.
               if (isset($settings->state) && (isset($settings->state->enabled)) && !$settings->state->enabled) {
                   return $this->isAdmin();

 * Hello Munir,
 * Looks good, no more problems, the pages can be edited again.
 * Please continue to develop this great plug-in, which has become indispensable
   for my WP installations, especially because of the possibility of linking groups.
