Dear Support Team,
Yesterday, we migrated to the latest version of WPDiscuz. Following the update, we found the following error message in our PHP error log:
[12-Mar-2026 13:10:28 UTC] PHP Fatal error: Uncaught Error: Class "wpdFormAttr\Form" not found in /home/w28e2juh6h76/webseiten/hello-world.net/wordpress/wp-content/plugins/wpdiscuz/forms/wpDiscuzForm.php:22
