Hi fsmed-regensburg, within that PTA Volunteer Sign Up Sheets Plugin there is an export feature which does a check_admin_referer() check and when this fails it returns the above error screen. Disabling the export functionality of that Plugin by commenting line #28 of their pta-volunteer-sign-up-sheets.php will likely fix this. I’ll see if there’s anything we can do on our side aswell but we’re all playing in the same ‘swimming pool’ that is WordPress Admin so things like this can come up.
