Jesus,
Make sure you followed the instructions re: templates.
- Go into admincp -> options -> vbnexus options
- At the bottom of the page, you'll see "Facebook Wall Feed Template COnfiguration Center", below that, click here. Do that
- On the next page, click "Save Changes"
- Reload the admincp->options->vbnexus options page , and the template ID's will be filled
- Click "save" on the vbnexus options page
This should resolve your template issues. It is important that you follow them specifically. If you're moving over from fbconnect, make sure you clear out your old bundles.
RE: Usergroups, this isn't just you. Right now, we're ALL waiting on IB to come up with the solution to that one.
RE: User registration email, maybe possible, but the user isn't technically "registering" through standard methods, so you need to allow for a few differences. Maybe IB can fix this, we'll see.
