Have you deleted/reset via general settings on 000webhost.com?
I did a reset like 50 times but I tried deleting it and making it again and that worked like a charm. Thank You so much! I hope the original poster was able to fix their website as well, I know I was able to see it and it looks pretty neat I even bookmarked it. Thank You!
Your website is working fine now. No 502 Error.
