I activated the plugin and nothing happened

This plugin will only redirect users who are viewing the site on a mobile device. You also must first update the redirect URL within the plugin settings.

How can I give my users the option to view the full site

If you want to use this feature set a link to “” anywhere on your mobile site. The cookie will expire after one day.
You may change the expiration time by changing the time()+86400 on line 43.

What about back to the mobile site?

This can be done one of two ways, you can either link to the mobile site directly ( or you can clear the cookie by linking to “” anywhere on your WordPress install.
