Sorry for the double post.
I urgently need help. After the upgrade I have this error on top of my forum:
Warning: array_merge() [function.array-merge]: Argument #1 is not an array in [path]/global.php(400) : eval()'d code on line 1153
My whole forum is completely messed up. For some reason this only happens if not logged in. So for guests. If logged in, everything is fine.
EDIT: OK I realized that after I disabled the Use 'Full File Cache For Guests (BETA!)' everything is fine. So there must be something wrong there. (And I did CHMOD 777 -R vbet_guestcache)
