I have an Omeka site with multiple (~20) contributors. All was working fine. Suddenly, since last night, users became unable to edit items: from the Admin panel, they see the items; they can click the Edit button; and then all they can see is "Edit Item #253: "The Furies" " and a blank page. As superuser, I am experiencing exactly the same issue. Other Omeka sites through the same provider appear to be working fine. Any idea how to fix this?
Thank you in advance.
