When I try to create a new thread I get sent to 'Page Not Found'. A couple things happen here:
1. If it's a pretty short post it will post.
2. If it's longer it goes to 'Page Not Found' but the error page is from my blog (my forum is in a subdirectory and my blog is in the root).
My webhost made some changes to the .htaccess and I thought everything was fixed but apparently not.
Any help on how to troubleshoot this would be great.
