No valid image was loaded

I've never heard of that error before and that message isn't coming directly from JFBConnect.

Doing a Google search for "No valid image was loaded", there are multiple reports of that error coming up when a Mosets Tree plugin called "Profile Picture" is enabled. Would you happen to be using that plugin? If so, is it necessary or can you disable it?

If that doesn't help narrow things down, can you let us know a site where we can test the registration process and we'll gladly help investigate further.

Thanks,
Alex

Glad I could help narrow things down. Should you need anything else, just let me know.

Finally, if you haven't already, please consider leaving a rating and review for JFBConnect, or our support, on the Joomla Extension Directory. It certainly isn't required, but is very appreciated:
