Forum:Photo Uploads Not Working

Hello. So I made a new wiki. It was a Star Wars Role-Play wiki. It didn't work because it wouldn't let me upload background. I made another one. Another fail. So my friend just amde it for me. My other friend joined the wiki and can't upload photos. Neither can I. Neither can the friend that made the wiki. We keep trying to but it won't work. Everytime we made the wiki we used the same theme. Is that the problem or is it the names of the wiki because on everyother wiki I can upload a photo with no problem. Can someone please help me because the wiki is new.
