SQL errors and etc

[DavidWWL]

I hope this is the right section of the forum to post this subject in.

This morning, there were html snippets displayed next to somebody's username on my forum.

I went to the maintenance area in admincp and ran the "repair tables" to see if that would fix the issue, and after that, started getting msql errors, and the site does not load any more (webworldlounge.com)

When I went back to poke around in admincp, it brought me to a screen saying that "There are currently 102 customized template(s) that need to be updated or reverted. Some sections of vBulletin may not function if you do not do this!"

I'm not sure whether it's safe to click on "revert" (see screenshot here: http://img29.imageshack.us/img29/396...dtemplates.jpg), or if I need to do something manually to fix/save these files so that they will be the same as they were before this problem happened.

Database repair was tried through cpanel, and resulted in many errors, examples from the generated report; I edited out the "ok" items to show just the error items:
