Thanks Reezo, but WP-FB-Autoconnect doesn’t work in my site.
I have tried also new update version (today), but nothing: I read comment on WP-FB-Autoconnect blog for search a solution but there isn’t.
The only facebook plugin that works for me, actually, it’s only BP-Facebook and I hope Andy update it.
I don’t know why, but WP-FB-Autoconnect (also this update version) doesn’t work for me: and there is only one other person that seem to have my same problem.
It’s a tragedy (((
Instead for me it’s the only one that works very very well (and I have tried wp-fb-autocnnect, Gygia, simple fb connect, Facebook Connect to Adam Hupp, Faux Facebook Connect -only for comment- and others)!
The only ones that work (for me) are Gygia (but only if you have a normal WordPress installation) and BP-Facebook connect (there is a very little problem with logout redirect). And more, Bp-Facebook gets also the (facebook) email of user.
I don’t love its method to work, but it works.
I have Buddypress 1.2.3 and WordPress 3.0 beta 1 (network installation with subdirectory).
The very great problem that I have with Bp-Facebook (at the moment) is the incompatibility with WordPress MU Domain Mapping: if my secondary blog mantains subdirectory url, BP-facebook works (too well).
But if I change a subdirectory url with a primary url (example.com/secondaryblog to secondaryblog.com) it goes crazy.
And this is a problem!
