installed ver 9 now login ends in a 404

Well that's not good! Looking at the autotune logs, it looks as though you rolled back to JFBConnect v8 (which is understandable).

For the error you're seeing, we can't directly understand how it's failing like that. It seems like something is trying to show the social login buttons incorrectly, but it's impossible for us to tell if that call is coming from within JFBConnect or from another extension. We can't find anything in JFBConnect that would be doing that though and haven't been able to recreate the error.

So, with that said, can you help with any of these details:
* After installing v9, did you enable the Facebook provider plugin (this is now a separate plugin)
* Do you have any other extensions that integrate with or show the social buttons from JFBConnect?
* Were you trying to login from SCLogin or the standard Joomla login area?
* Was this a social network login and, if so, which network?
* What page threw the 404 error? Was it a landing page on your site, the home page, etc?
* If you refreshed the page, did it still show a 404, or does it go away on refresh (indicating it only happens right after the login).

Sorry for all the questions, but anything you provider will help us understand further. If there's a development site we can test on as well, that'd be fantastic.

Thanks,
Alex

Thanks for all the details. We're looking into ways to recreate this, but are unable to yet. We'll definitely keep an eye out for related issues though and, if there's something within our install package we can improve, we surely will.
