1) You're site is using JCH Optimize, which is compressing and moving our scripts around. Our Error Check tool can't find JFBConnect in the output. I'd recommend running Autotune and testing in general with JCH off.
2) We don't currently support Channels for Google to read or post to. Google+, in general, is diminishing in reach, their API hasn't been updated in years and Google+ is simply not a focus for us. Google+ integration isn't requested much by our users either (and it's declining), so it's not our focus. As for Channel features that could be done in Google+, I believe we could pull a feed in, but posting to a Google+ 'page' is not something their API supports as far as I know. So, even if we were to work on a Google+ Channel, it would be limited to display only.
3) You need to go into the Plugin Manager and enable any Open Graph plugins for extensions that you want to customize the objects for. For more details, you may want to check out our "Open Graph Tags" section of our
Quick Start Guide
.
4) We don't have any updated videos yet. Facebook is constantly changing their interface and JFBConnect v7 was just released. We are working to update our documentation continuously with the Quick Start page being our newest addition. JFBConnect supports a ton of features. We try to tie them altogether in an easy-to-use manner, but we understand there is some effort it takes to get things going. We're always trying to simplify the process, but when you integrate with 10 different social networks, and need to create apps with each and support almost a dozen 3rd party extensions, it's not easy to make anything 1-click to setup.
If there's any specific issues you're running into with the above that we can help clarify, please let us know and we'll gladly explain further.
Thanks,
Alex
