“Awaiting Moderation” link not working!? PHP??

I haven’t had a problem with this before but now when I click to try and approve a comment, the page goes blank except for “54”. that’s it. Same with another site.. it’s not a WordPress page but same thing.. I hadn’t had any problem with all my “members” pages on my fanlistings, except for one.. where it keeps showing a blank page that says “35”.

Is it something that the user might’ve written that messed up the coding?? I’m figuring it might have something to do with PHP since the WordPress and my fanlistings are PHP … how can I fix this? thanks!

Edit: Oooookay, so now the comments in moderation link worked.. but it’s still wonky for my fanlisting members page… gah. so weird.
