Forumlar / Cotonti / Support / major php crash???

i really doubt that this was caused by the pagination.Last time i saw it on seditio(elder of cotonti).The settings for post pagination are located in "admin.php?m=config&n=edit&o=core&p=forums"

I think you should test the site on localhost again.But this time with the used database and the entire copy of your site(that is in the internet).If you want help with the testing - write to me by ICQ cause it will be difficult to do give you advices by forum
