Hello,
when I try to change something in the following pages (see hidden content), it says "checked out" and "you are not permitted to edit this page because one more user is already checked-in", but we only have two users and I am the only one working in Joomla. Nobody else is checked in and all the other pages are fine to edit.
I created a temporary admin-account for you (also see hidden content).
Please checkout whoever is supposedly checkin, so I can edit pages again.
Thank you very much!
