Probably ver 2.2 isn't a good choice at the moment for a working site.
You should consider to use 2.0.13 that's more stable and bug free than 2.2.
Infact this site, that's the official Xoops'site, still use 2.0.13 and I think they'll continue to use this version for much time because 2.2 was a premature version born without necessary tests and without compatibility
