Linked login not working

What version of Joomla are you using? The extra_query field was added in Joomla 3.2.2, released earlier this year. That field is meant to support upgrading of subscription based extensions, like JFBConnect.

If you're not on 3.2.2, I'd highly recommend upgrading as there are multiple updates in 3.2.3, 3.2.4 and/or 3.3.0-3.3.1.

If you can't upgrade for some reason, we'll be able to provide you with a minor bit of code to remove that SQL query.

If you are on Joomla 3.2.2 or higher, please go to the Extension Manager -> Database area and click the "Fix" button. It should update the Joomla database table appropriately.

Finally, after this post, I'm going to move this thread to the JFBConnect 3.3 area, so look for it there.

I hope that helps!

Thanks,

Awesome! I'm glad to hear that helped get you going, and sorry for the confusion. We don't normally support such 'new' features, and try to have better backward compatibility built in for older releases. In this case, we just screwed up, I'll be honest.

Upgrading Joomla is always a wise thing to do, just to make sure you're not too out of date and have all the bug and security fixes applied.

If you need anything else, please let us know.

Thanks,
Alex
