The new release of JFBConnect just came out on Wednesday last week. We have the
Open Graph Actions for Joomla
configuration guide, but we agree that we need to do a lot more for examples and information about how to use each of the plugins. The Custom Object plugin is extremely flexible, and we're excited for users to use it, but at first, we're focusing on the 'built-in' actions/objects as those are easier for most users to understand.
As for what's next, the main feature for the next release will be Joomla 3.x support. Open Graph Actions are definitely something we'll be continuing to improve for ease-of-use and new features. There's a lot more that can be done, but we wanted to get the first release of it out and check. There are other things we have plans for, but they're not ready to be announced as things change.
Finally, as for your current issue, if you're still having problems with the new release, please let us know!
Thanks,
Alex
