How do I set it up? Sorry for my dumb question but I really don't know how to set this up for my site? I bought an advance hosting and it says MobileView is free for the advance hosting package.
It looks like you already have it set up on one of your domains. To use it on the other domain you need to use our hosting for that domain as well.
To set up MobileView on the other domain click on the domain's name server settings. Click on the Dynadot Hosting tab. Advanced Hosting should be selected and then click the MobileView checkbox. Click the "Use Dynadot Hosting" button.
