The most common reason for this is a popup blocker. Sometimes the event organizer will request you to Like their page on Facebook. In order to this, a window will appear asking you to login to your Facebook account. If that window is being blocked, it may appear you are stock on a “Loading Facebook” page and nothing is happening. If this is the case, we suggest disabling the popup blocker and trying again. You can also open a new window and log directly into Facebook and try purchasing again. Lastly, if you do not have a Facebook or do not want to bother with you, you can always click the “Skip” link located right under the “Loading Facebook” text and go right to the shopping cart.
