problem in loging in

Thanks for giving the full error message, it helped to narrow things down quickly. It looks like there was a change in Facebook's API that we were unaware of. They have removed the following fields:
* Likes & Interests - Activities
* Likes & Interests - Interests

You'll need to un-map those in the JFBConnect -> Profiles -> Facebook area from any extensions you're trying to import that data into. Then, the error shouldn't happen anymore.

I hope that helps, but if you need anything else, just let us know.

Thanks,
Alex

Can you disable any caching you have enabled, either in the Joomla Global Configuration area or any 3rd party extensions you may be using to optimize your site? My guess is that that is the cause of the duplicate clicking of the Facebook button to login.

As for the 2nd message, it sounds like you have an account already on your site with the email address you used for the Facebook account. Can you check your user manager to see if such an account exists? If so, that's normal behavior. You can also enable the "Automatically Link Users by Email" option in JFBConnect to make an immediate connection between the social network account and the existing Joomla account on your site.

I hope that helps,

That SQL error could definitely be part of the problem. It sounds like a not-complete upgrade of Joomla. Can you go to the Extensions -> Manage area and click on the Database tab. There may be some errors listed there. Either way, try clicking the "Fix" button to see if that helps fix things up for you.

As for the About Me field, do you have that properly configured in the Profiles area of JFBConnect to import? If so, which field are you importing? Also, are you testing with a Facebook user that is an admin of your app or from another Facebook account?

Thanks,

Can you help explain what you mean:

in the backend its all imposted in the profile

Are you saying you have JFBConnect configured to import the profile data, or are you saying that you see the profile data for the users in the admin area?

maybe the problem is from the developers

Those are the standard permissions and things look to be requested properly.

I just looked at the admin area of your site and disabled the Custom DB plugin since you don't seem to be using it. I also see that you have the JomSocial, Kunena and Joomla plugins enabled. Which system are you using to store the user's profile. Most sites don't use 3 different profile systems for their users as it will get confusing.

Let us know more about what you're trying to do and we'll gladly help however we can.

Thanks,
Alex
