I faced same issues, my luck today i decided to finally start running the community again, i use hosting with hostinger with SSH access, so after complete installation
versions installed
Php 8.2 and 8.3 without public path
So installation is all good as usual after installation when you install any extension it will do normally and then refresh on page saying update flarum where you have to put database password again like i tried all methods but as soon as you install a extension it will ask you to update flarum with database password and right after that you will see your forum normally and then you go administrator-> Basic -> it will show no settings
I thought i am doing’s something wrong until i saw this thread.
