Omeka: Cannot Edit Items


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.



Just to double-check, is this site on If so, it could be related to some renewal issues we were addressing over the weekend. In that case, it will be best to contact using their contact form.

If not, have you made any changes, such as enabling a new plugin? It might also be worth turning on error messages to get more information.
