Ill start off by saying im not the best with linux servers so this could just be me
When i try and visit my map, hosted on my apache server i get the error
Could not retrieve configuration: Forbidden
This error started appearing after i changed to a Multicraft control panel, i have tried giving every folder involved (server, server plugins, map, public html) the right permissions, tried giving them 777, tried adding the multicraft user, nothing seems to work, please help

If it's webserver, Check your apache config/htaccess
If it' standalone check database is accessible with the login config
Check php modules
