Subdomain Forward

Hi. Welcome to the forum.

If you log in to your InfinityFree account and go to Control Panel > Redirects

You should be able to set it up there. Make sure your .htaccess file is not redirecting to somewhere else too. Also check the settings for your store software to make sure it’s not redirecting to somewhere else. (e.g. forcing https).
