JFBconnect System Plugin conflict with Jreviews Template 3

Are you using JomSocial as well? If so, there's an issue with the SocialProfiles - JomSocial plugin that's causing templates to not be assigned properly when that plugin is enabled. There's a quick fix if that's the problem.

If you don't have the SocialProfiles - JomSocial plugin enabled, can you leave the JFBCSystem plugin enabled and disable any other Open Graph or SocialProfile plugins you have enabled? If things work then, please re-enable each of those one by one to narrow down which is causing the problem.

Finally, you mention 'crashing'. I'm assuming you just mean that it can't be assigned, like you mention in your first sentence. If you're seeing an error or other message though, please let me know.

Thanks,
Alex
