FB.getLoginStatus not calling its callback

Question

The title really says it all. Under some (undetermined) conditions FB.getLoginStatus() just stops working and won\'t invoke the callback I gave it. The only interesting clues

Answer 1

As others have posted, you must be accessing your site at the same URL that facebook expects. For example if facebook has a callback "example.com" but you're browser has "www.example.com", that can cause this problem.

In addition, if third-party cookies are not allowed by your browser, you may also see this problem. Or you may see the callback erroneously reporting the user is not connected.
