I'm trying to update my WPMU from 1.2.4 to 1.3 and I was able to get the old files backed up, the new copied over and the proper files/directories copied from old to new, and even ran the database upgrade script.
After all that, I'm getting a ton of page error, headed by this one:
Notice: Undefined variable: current_site in /Volumes/DataHD/WebServer/Documents/weblog/wpmu-settings.php on line 2
I've looked into wpmu-settings.php and I see that this is what is controlling if it redirects to the wp-signup page or not, but I have 4 blogs already in my database, so I'm not sure why it can't find the blogs I already have set up.
Any ideas where I can look, or solutions? thanks
