unable to log in to my site after update

Robert,
That link seems like a normal link during the authentication process.

If you're getting a white page, that means there's a PHP error occuring. Please set the Error Reporting setting to "Maximum" in the Joomla Global Configuration area. That should show a real error message instead of just white. Hopefully that helps you narrow things down, but if not, let us know the exact error and we'll help however we can.

Thanks,
Alex

Glad to hear you got it going... and that it wasn't JFBConnect.. we get blamed for oh so much

If you need anything else, just let us know.

Alex
