JFBconnect 4.3.3 a lot of warning in front page

Iveth,
If you're still seeing warnings, please post what the warning is. If it's different than the ones in the first post of this thread, it's best to start a new topic as your problem is different that the one originally posted about in this thread.

For your other issues:
* I'm not sure what the "Joomfish System Plugin not enabled problem" is. That doesn't sound like a JFBConnect issue, it sounds like a Joomfish issue.
* The {JFBCLiveStream} tag was removed in JFBConnect v4.3. Facebook discontinued that plugin in October and was showing the Comment box in it's place. If you're using the LiveStream tag or module, you should replace it with the Comment box.

Hope that helps get you started. Not sure what the Joomfish issues are, but again, those likely aren't related to JFBConnect. If you're having specific issues with Joomfish, please create a new thread about that, unless you think they are related to the warnings above. I'm a little confused about the issues you're having as they all seem to be mixing together.

Thanks,
Alex
