Module not working for me.

I don't know if it is just me or what but I can't get this module to work. When I go to the settings for embed filter and try to add sites I cannot because there is no "update" button or anything like that. Instead there is a truncated sentence and a missing image "Each host name or base URL from which, or " <--- it cuts off right there. This is on two different installations of drupal. Please help.
