Hello

Upgraded from 2.7.4 to 2.8.0 (Automatic upgrade)

The gallery seems fine.

I admin, and click on "Advanced Menu Manager" I got this error:

Fatal error: Call to undefined method tabsheet::tabsheet() in D:\xampp\htdocs\pwstsh\plugins\GrumPluginClasses\classes\GPCTabSheet.class.inc.php on line 52


Can you please help?

Regards from Paal
