Facebook Bug Affecting Fangates and Fanpages.
There is a new Facebook bug that has changed the behavior of Fan Gates for the default landing tab. If you use the Default Landing Tab setting on your Facebook page and show non-fans different content on your tab this bug is affecting you, and it’s affecting anybody else who has a Fan Gate.
The Issue:
Normally, when non-fans visit your Facebook page, they will be sent to the page tab you have set as your Default Landing Tab on your standard page settings. When visitors press your Like button, Facebook would refresh the page and send the user back to the same default landing tab, showing them the fan-only content- ie. the value item, download, link, offer, discount or other promotional content or simply a welcome message or acknowledgement that they’re now in the ‘fan zone’.
The Bug:
The new Facebook bug #19778 breaks this process. Instead of taking the new fan back to your default landing tab, the user is now sent to your page Wall!
The good news is that Facebook has responded to the bug saying they are investigating. If you want to track the bug, you can check this link: http://bugs.developers.facebook.net/show_bug.cgi?id=19778
We’ll keep an eye on this situation, but for now, we have created various solutions that deliver a great user experience despite buggy behavior from the code!!
