Grant Extended Permissions does nothing

Hi,

Nothing is happening when I click on Grant Extended Permissions, other than a javascript error in FF/firebug:

h is undefined
[Break On This Error]

...dow.open(b.url,b.id,c));if(b.id in FB.UIServer._defaultCb)FB.UIServer._popupMoni...

all.js?ver=3.3 (line 22)
h is undefined

I've disabled all plugins and reverted to the TwentyEleven and 2010 themes, but still get the same error. I also just upgraded the plugin from version 1.5.1, where I had the same problem.

I know the FB app is working because I've had Simple Facebook Connect working fine.

I've also had this Ultimate Facebook working well on other sites... any suggestions?

I'm not using login with facebook, so let me know if you need some login credentials:
