OPEN Xenforo Theme

[coolkoekie]

Hey guys,
I really hope you guys can help me cause nobody else can,
I installed xenforo and i want to change the time, i used multiple themes but when i enable them the browser just turns white, I did the map with all pictures and stuff in the styles map with filezilla and then uploaded the xml online, What am i doing wrong?
Thanks
