Hi,
It looks like your website has a broken code on it or the server can’t handle your code maybe it’s just to heavy.

Also what Forum Software did you use?

An error 500 and 502 are very different and have different causes. A 500 response usually means that your website code crashed. This could be caused by anything, but figuring out what the actual error message is is the best place to start: https://infinityfree.net/support/http-error-500/

Ouch, that’s expensive. Do you have a license for that? Note that using pirated software on here is strictly forbidden and if we find such software, your account will be terminated without any opportunity of recovery.
