Hello Paul

I try to update the forum (6.2.2 -> 6.2.3 - 6.2.4) and I meet this error when the button is clicked Upgrade:
Fatal error: Call to a member function isadmin () on a non-object in / home/milouch1/public_html/forum/admin/adminend.php on line 10

My two other scripts were updated perfectly.

Do you have an idea about this problem?
Thank you for your reply.
Regards.
Francis
