Aarelith why https://discuss.flarum.org/index.php got 404 error? i got same problem when i 301 redirect non-www to www "domain.com" to "www.domain.com/index.php"
ChristopherKhawand It is because you can only use one URL in your flarum forum, that is specified in the config.php file. So domain.com/index.php is not the same as domain.com or www.domain.com
