Facebook comment plugin comments disapear after refresh

Question

I tried adding the comment plugin for facebook to my website. Its a neocities domain so i dont know if that has anything to do with it. I made a new app then went here https://developers.facebook.com/docs/plugins/comments/ and got my code and put it where it should be put. The box works but as soon as i refresh the page the comment disapears. Here the page: http://thepokeprognostication.neocities.org/forum.welcome.html
