White Index Page (RevCms)

Everything on my new retro is going fine. When someone else tries to enter the hotel they just see a blank white page. Not even an error message. I can access everything. I've tried to port-forward, but i can only go to the retro on my wi-fi. anyone else with a different IP can't see anything.

Just buy a VPS can get them for like $10 now.

Problem solved.
Would be laggy as hell if you port forwarded it anyway.

I don't wanna buy tho. Know of any other methods?
