I installed "plesk panel" on my server first.
I installed flarum with the command composer create-project flarum/flarum . --stability=beta
"Plesk panel" made nginx settings. I have set the Public folder.
sudo chmod 775 -R /var/www/vhosts/asgard.gen.tr/httpdocs
I am setting the file permissions but for some reason it still does not accept.
The /var/www/vhosts/asgard.gen.tr/httpdocs directory is not writable.
