Problem with Install on 1.7

It sounds like you've already checked, but definitely make sure that the Joomla 1.6/1.7 versions of the component and plugins are installed.

Then, if it doesn't still work, try the following:
1) Disable any profile plugins (if any are enabled).
2) Go into the Configuration area of JFBConnect and simply hit "Apply". You don't need to change any settings, though you're free too.
3) Try re-enabling the profile plugins and hopefully you should be good to go.

If that doesn't fix it, instead of uninstalling any plugins, try disabling them in the Plugin Manager, and see if there are any circumstances that it does work with (no plugins enabled, etc).

Hopefully, the above steps are it, but if not, let us know.

Thanks,

No problem for the weekend response. We understand that people work on their websites on the weekend, and do what we can to help. Sorry you ran into a weird bug in our software. We're working to fix it in the next release, but it shouldn't affect you at all anymore.

Thanks,
Alex
