There is a new Facebook bug (again) that has changed the behavior of FanGates 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 may be affecting you.
When visitors press your Like button on your default landing tab, Facebook is sending the user to the Wall instead of back to your tab. This is happening for pages which are active in Facebook’s testing of the new Recommend this Page feature.
A bug report has been filed with Facebook, you can follow it here.
