Weird Posting Issue
 

Hello, when I post post on my website's forum it randomly picks out an old thread and posts that information instead. As well, settings, posts and members are being deleted at random. For example, I would post: Testing123 --> as a new thread and instead it would post "Yea that is ok" ----> post made in an old thread This seems to be happening to all members and started yesterday out of the blue (the settings weren't altered in any form). As well, posts are being brought back that were previously deleted. Could this be a DB problem? Thank you. PS I have not made any edits (other than create a few new forms + calendars) and no hacks have been installed or addons.
