I've just upgraded to 2.5.2, added two users and two new forums.
I'm now getting the following error when opening the main forum page:
Warning: Unable to access /home/virtual/site210/fst/var/www/forum_data/include/theme//err.inc in /home/virtual/site210/fst/var/www/forum_data/include/core.inc on line 69

What could be the problem?
