address line error

example my site:

site opens up nicely But
deneme.com
explosion is happening 🙁 category icons do not appear

defined in "http://www.deneme.com/ " config file.

I tried this code

RewriteEngine On
RewriteCond %{SERVER_PORT} 80
RewriteCond %{HTTP_HOST} ^www.?deneme.com
RewriteRule ^.*$ http://deneme.com/$1 [R,L]

never happened again

MesutDeniz make sure you access the forum via the url you define in config.php.

You should use apache redirects or the https://discuss.flarum.org/d/19307-canonical-url-redirect extension to make sure the website is only accessible via the domain and protocol you defined in config.php.

Ideally that URL should be HTTPS.

When I go to your domain I don't see a Flarum website.
