I'm having a similar but maybe stranger issue? My Standard Version link works unless you do something odd. If I go to the standard page from the mobile one, then go to a menu item that isn't on the mobile site, then click mobile site and go back to mobile, THEN click Standard Version, it loads the same article as my mobile home page, except there is no template at all.
I am very new with this and maybe I have this setup poorly. I made a new Joomla menu for mobile site things, made an article (called Home) and put in on that menu, then told MJ to make that the mobile home page.
This is the "force as homepage" url - index.php?option=com_content&view=article&id=73&Itemid=135 or I can just type "home" since I have the search friendly urls.
The url is picking up "home" in the name like /home?device=xhtml instead of just /?device=xhtml and that is messing it all up. I think a good solution for me would be that the links just go directly to each home page, rather than staying on the page they are on. I'll try to mess with it. Any advice?
