Error when I try to save a resource

Hi Everyone,

I just tried to update an email address on the contact page for a client of mine. Very simple, right? When I hit "save" on that resource, it gave me an error pop-up box with this text: "An error occurred while trying to save the resource." Does anyone know what I should fix first or why this would be happening? I have not modified this modx site in a while, so may be missing something super obvious. Thanks for any thoughts!

Does an error occur if you try to save any other content? Try creating an unpublished test page with some simple text.

Two things come to mind. The site_content table may need to be checked and repaired. Or, the hosting company may have enabled or re-configured suhosin, mod_security or some other security feature that does not allow the use of email addresses in form postings.
