Help Needed - Post data and thread titles not displaying

[MarineColorado]

Hi All, I was wondering if someone could provide some assistance. I run a forum for a local club in Denver. For some reason a lot of the text is not showing up now, specifically in the Threat Titles when browsing a forum and the post data when viewing threads. I have checked everything I can think of. Server looks fine, even rebooted it to be safe. I have no idea where to look from here.

I did notice also when I try to post a thread it comes back with the following error. The following errors occurred with your submission
