Carolinechurch.net is currently unable to handle this request. HTTP Error 500

The Omeka database does not upload, upon clicking on the link “Cemetery & Artifacts Database” (www.carolinechurch.net).

Get an error message “carolinechurch.net is currently unable to handle this request. HTTP Error 500”.

Anybody can help, fix the issue?

Thanks,
T

The first thing to do would be to activate error logging and the let us know what the logs say.
