software1223 I installed it correctly, the forum is open but neither post is shared nor anything, it always says the requested page was not found
luceos Sounds like your webserver isn't redirecting requests to the php file. What webserver do you use? Apache, nginx or something else?
luceos software1223 I have no experience with cpanel sadly. But I assume Flarum is being served from its installation path and not the public directory. You should be able to customize that for the website. You can potentially ask this question on the cpanel community or at flarumtr.com.
