posting problem

Sometimes I get the message shown below when I click 'Post'.What problem does this indicate?I'm using the Mozilla browser.

Fatal error: Call to a member function on a non-object in /var/www/redhotpawn.com/board/threadcreate.php on line 7

I also had this message the day of the outage...............''fatal error'' sounds weird uh?
