JFBConnect does not work at all in JomSocial

The Javascript that JFBConnect requires is not being loaded on the page. You have JCH optimize enabled which is trying to compress all the Javascript together into a file. JCH loads the PHP file media/plg_jchoptimize/assets2/jscss.php which is what's supposed to compress everything. However, you can see in the console that that file is throwing a Javascript error.. followed by a bunch of other Javascript errors for jfbconnect, joms (JomSocial), SqueezeBox and more:

You'll need to start with fixing, or disabling, JCH Optimize which should clear up your Javascript errors and hopefully get things working.

I hope that helps,
