COPPA Form - CrossfireForum.org Gallery
I am not sure what your techimo comment is about if I hit register it goes to the photopost registration script. Your gallery is therefore installed as a standalone
It is suppose to be installed to integrate with your forum but it is not. I would suspect from what I see you have left your install script online and someone has decided to break it so you would need to properly reinstall to integrate with your forum and then delete the install script
That should correct your issue.
