A long time ago I have installed and managed a forum based on FUDForum. SInce a few years I have never touched it.
It has a low traffic, but it is still used. Also is installed on old server, on which I'm just a user.
The FUD engine (according to core.inc) is 2.7.5.
Via RSS feed I have noticed spam on my forum.. However when I'm trying to login, I'm unable to do it.. On /index.php, after providing credentials, I'm back on root page with no profile logged. On /adm/index.php I'm asked for credentials and not going futher.
I was trying to upgrade to FUD 3, but PHP is on version 4..
For FUDForum 2.7.6-2.7.7 I haven't found any upgrade script..
