[Plugin: Mobile Domain] Mobile sub domain won't work

Hi, I’ve setup a subdomain for this plugin and made all the necessary changes in its settings but it just won’t work. Its meant to redirect my mobile users to a subdomain I’ve created and the theme I specified in the plugin’s settings.

Everytime I try to access this link https://m.popularitybar.com in my browser, I get the “Index Of” page, instead of my website with its mobile theme I specified in the plugin’s settings.

But when I try to access the same link anonymously using anonymouse.org It works perfectly. I’m not sure if this has anything to do with cookies. I really need help on this. Thanks!
