We have upgraded vbulletin from 4.1.7 to 4.2.2 today.
Getting this error message right after installation:
Non-static method vBSEO_Storage:

ath() should not be called statically in
In functions_vbseo_pre.php we changed:
from:
function path($type = '')
to:
static function path($type = '')
Also tried:
public static function path($type = '')
With both modifications we don't get the error message anymore, just a blank page.
(internal server error 500)
What can be the solution?
Hope we can get our forum up and running again.
Thanks in advance.
