I held an event on our company's Facebook page. It is a fan contest that users will contribute their photos on our event page and we will select the winner based on times of "likes".
Most of the posts work great, but some of the submitted photos cannot be "Like", "Comment" or "Share" on the wall. (These photos can be shared or like after click in). Is there any configuration I can do or I can ask the submitter to fix in order to solve this issues?
