Weird replacement - please help!

[X-Fan]

G'day all,

For some reason my vBulletin is replacing all apostrophes with a backslash in front of them. Instead of a ' it's now coming up as a \'

I'm not sure if it's a recent hack that I installed or not, but could someone point me in the direction of the right file or template to check on this?

Cheers,

[X-Fan]

Even weirder, it seemed to only be in the one thread:

http://x-mencomics.com/xfan/forums/showthread.php?s=&threadid=7577

Take a look through some of the posts after the first one and you'll see \' instead of ' in them.

The first post had also been affected, with the big images' URL having been changed somehow to:


http://x-mencomics.com/"http://x-mencomics.com/xfan/images/previews/0702/XXM016crx.jpg/"


Any ideas where to look for the system doing this so I can see what's up?
