Rich,
I'm very sorry for the delay in getting back to this and thank you for bumping it. I somehow glazed over your original request and sincerely apologize for not responding sooner.
To test, all I did was:
* Click Login with Facebook
* Fill out my profile on the registration page
* I was automatically logged in
* Went to the page you mentioned
The site immediately tried to re-log me in. I also see the issue on the "Race-Reviews" page, and likely others.
The issue does seem to be from the Include Component plugin. We've never used that plugin. I've honestly never heard of it, but that doesn't mean anything 'bad'. From the description, you use a tag like {component ..}. If you remove that tag from the page, does the auto-login issue stop?
The reason that I'm leaning toward that plugin is because it's causing our JFBCSystem plugin to be triggered twice on the page, and so if you look at the HTML, you'll see 2 inclusions of the all.js file. The second is directly under the note about using the Include Component plugin where it puts the following comment in the code:
<!-- Plugin Include component version 1.13 by Mike Reumer
Since the Include Component plugin is calling our code twice, it's likely bypassing our checks that are meant to prevent a duplicate login. Each initialization of our code will 'detect' the user is logged in and see if they should be automatically logged in. Since that is happening twice, the second time is likely skipping some of our checks because JFBConnect isn't prepared for 2 authentication attempts (or it's even thinking the user is intentionally trying to log in again).
We can investigate the Include Component further, but I don't think I'll have an immediate answer for you at all. I'd love to hear if disabling the tag on the pages that break works for you. Until then, the only recommendation I'd have is to disable the Automatically Login Facebook Users setting in JFBConnect as that should prevent the problem altogether.
Again, sorry, but I hope this helps narrow things down for you.
Thanks,
Alex
