Encountered an error when I try to see items


When I click the title of any item in my Omeka, it shows an error message, saying that "Omeka has encountered an error." This is the link (http://sonzogno.cci.fsu.edu/items/show/3455)

It used to be working, but recently it stopped working. Recently, I tried to change some display stuff, but I didn't do anything further than the functions provided by Omeka (no additional coding).

I don't what's going on there, but I need to make it rework as soon as possible. Could you give me any comments on this issue?

Thank you for your help in advance.

The first thing to do to track down the error is to follow the link on the error page to the instructions on show error messages.

Turning that on will give much more information to work from
