I have recently developed a strange error after the following sequence of events..
1. Got Hacked
2. Rebuilt forum on a subdomain
3. Used impex to copy over posts, threads etc
4. moved forum back to original domain
Everything is working perfectly except for 'New Posts' (do=getnew) and one particular forum. Both lead me to the page you can see on the attachment.
I know there are new posts on the forum and i have over 2000 threads in the effected forum.. just incase you were wondering
Any ideas what could have caused this, or even better.. any ideas how to fix it?
