Couldn't read config file config.php
 

I upgraded to 5 beta 14 from 4.1.11 Alpha.

After I logged in to the admincp, I can not see my old threads or posts there. The forum was disabled so I enabled it back.

If I try to go to the forum itself, I receive error:

The config.php file is in the includes folder and chmod to 644. What is the problem with the upgraded forum?
