CAn't post in Viral Videos

I'm trying to post a video clip, using the [.video] tags (with no . obviously), and I keep getting an error:


Fatal error: Cannot instantiate non-existent class: m2f_forum_post in /homepages/21/d144609245/htdocs/forums.gridironfans.com/includes/functions_post.php on line 383

 

The server, that host the site, seems to have problems

 

Problem corrrrrrrrrrrrrrrrrrrected!!!
