The requested resource was not found on new installation

I installed flarum on aapanel (ubuntu 20.04) with pockethold. But now showing 404 error on /admin or maximum page. I didn't do any changes on file.

ahtasnim this usually is an issue with url rewriting. What webserver are you running? Apache? Nginx?

It's openlitespeed server.

It's fixed. Just uncheck the "Write access log" option. 🙂
