I am using Joomla! with the Fireboard component and host with hostmonster DOT com.

When I delete a post on the forum, or attempt to recount the forum stats on the back end I get an "internal server error." Joomla! people say the problem is not their software, the Firebaord people say it is not their software, and the host says it is not on their end. What can I do to remedy this situation?
