Login works, but I dont see a facebook LOG OUT button

What are you using to add the Login with Facebook button? The {JFBCLogin} tag? If so, you'll need to add it like {JFBCLogin logout=true}.

If you're using the JFBCLogin module, that should definitely have one, and I'm not sure why not.

Hope that helps, but if not, let us know.

Thanks,
Alex

Karel,
JFBConnect will work with that no problem. There's multiple options there.

First, we'd recommend enabling the "Automatically Link Users By Email" setting. When a user first logs in through Facebook, if a Joomla user exists with that email address, their accounts will automatically be connected together.
Also, the "Full Joomla User" setting will allow a user to login with an existing Joomla user (if the above setting doesn't automatically link their accounts) so they can connect that way.
Finally, the JFBCLogin module will show a "Connect with Facebook" button for Joomla users that login that haven't logged in with Facebook yet. This is good to enable on your site before you remove the Joomla login so that users can start making the connection between their accounts when they login through Joomla while still possible.

Hope that all helps!
Alex

Alen,
There's a bug with the Facebook Javascript library that is not properly deleting it's own cookie on some sites. We're looking into the cause and if there's anything we can do to fix it.

Until then though, if your site is affected, we'd recommend disabling the "Automatically Login Facebook Users" setting in JFBConnect so that the user can successfully logout.

Also, in the future, please create a new topic unless your issue is directly related to the topic you're replying too.

Hope that helps,
Alex
