I havent been able to get 2.2 or 2.2.2 working on my site either. I did fresh installation, cant get the login box. The documentation doesnt mention, that you have to run xoopsupdate.php after installation.
IMHO, 2.0.13 works great and 2.2 is indeed a mess, have already spent many hours figuring out and posting here without luck.
