Hello, I didn't make anything from my end. The forum stopped working and all what I get now is blank pages. I contact my hosting company, and they said that forum loading normal when visited from a Proxy server. But from normal browser all what they get is blank pages. I check it my self and really from different proxy website forum work. But not from Normal browser. I have VPN, so I checked from different countries and from Mobile network and from Windows and from Linux All what I get is blank pages.

Please check to see if you are running PHP 8.0.17. If you are, disable zlib, as that is what is causing your issue. There was an update and PHP have broken things. We have a workaround in the next upcoming release for this

Thank you. This solved my issue.

Glad to hear you found the solution to the issue.
