I've tried multiple browsers (Chrome, IE9, Opera10), operating systems (Vista, Win7), connections (home, work VPN), different PCs, but can't for the life of me log in to my Flyertalk account anymore using Facebook connect. My original handle is -Heathcliff-, and I don't think I ever set up a regular login/password.
I am logged in to Facebook. On Flyertalk, sometimes the Facebook connect button won't load at all:
If it does load and I try to log in, a cross domain receiver page pops up and that's it. No further progress/redirect/login:

.
While I did occasionally experience the non-loading Facebook button issue in the past, I was always able to log in as long as the button did load. Not so since last night.
Any idea what's wrong here? I'm happy to transition to a regular account as per the
other thread, or have this one merged with my original one, though I'd still like to be able to use Facebook connect eventually.
