atomicturtle.net has been operational for over a year with 48 installed modules, 3,000+ pictures in the gallery, and lots of other stuff. My server is a Linux box in my house and I am running six other XOOPS sites on it with no issues.

I upgraded to 2.2.4 and now I can't log in. (The login page is viewable at atomicturtle.net/user) When I log in I get the page that says I just logged in and then I get redirected back to the index page as normal. However, there is no admin menu and none of the modules, like gallery, wordpress, and articles show admin controls.

MySQL via putty shows no apparent corrupted data, all appropriate directories have 777 permissions, and xoopsinfo says everything is fine. I just can't log in.

I have two other XOOPS sites on the same server that are running 2.2.4 with no issues.

What on earth have I done???
