So I am not a developer. I have inherited a web site which did not have a mobile site. I added this nifty plug in and expected it would work. Only it doesn't: on my android I keep "We're sorry - there is no such site" error message when we go to mk.myurl.com. And there is no way to easily find what I need to know to fix this. I suspect the site was set up by someone who knew what they were doing and that they downloaded WP software and set something in the configuration files which needs to be altered. Or maybe not. Help.
