Forum Fatal Error after upgrade to 4.0.5
 

Just upgraded to 4.0.5 from 4.0.3 and now I can't open threads, I get this error message

Fatal error: Call to a member function query_read_slave() on a non-object in /home/mysite/public_html/forum/includes/class_postbit.php(321) : eval()'d code on line 92

Anyone know why? Is this a common problem?

I've been using and installing/upgrading vbulletin for 6 years and not once have I ever encountered any problems... until now!
