The error in Overview

The SSL cert problem can happen on any system, but happens more on development servers. This is basically if your Apache installation doesn't have root certificates installed to which it can validate the calls to Facebook (over SSL).

In the Facebook API configuration area, we have a convenient "Don't verify SSL settings" (or something like that), that you should enable to get rid of those errors.

The undefined weekly_active_users is warning that we fixed (either in 3.0.2 or the upcoming 3.1 release, can't remember). This occurs when communication can't be established with Facebook, either from the SSL error or no API keys being set. We check for this can in the newer releases and prevent the warning.

Finally... (yeesh). The last XMLRPC warning is due to how we do version checks. Your running >=5.3 of PHP. The XMLRPC library included in Joomla is unfortunately old and throws this warning. We're hoping to have an improved system in 3.1, or sometime very shortly after, to prevent these warnings from showing when you have Error Reporting enabled.

Hope this all helps.

Support is about 90% of what we're selling. JFBConnect is a great extension, but Facebook in general can be a bear to get going if you happen to run into issues.

I'm assuming this means you're good now, but if not, you know where to find us!
