I am looking for a add-on for redirecting the non-www version of the URL to www-version or will it be better to do this with .htaccess file as done with normal html websites?
i set the url of my forum with the "www" part, but when i accessed it without it, some style-resources are not loaded correctly. Also when i was logged in at https://www.example.com, i had to re-login at https://example.com ... very weird, but now it works perfectly.
