When I try to update mobile theme support and choose what template to use I always get an error message when on my mobile device.

“sorry but the required template file could not be found or could not be opened.

This can be caused by a missing/corrupt theme or theme file. Please check the Simple:press Theme List admin panel and make sure a valid theme is selected. Or please check the location of the selected theme on your server and make sure the theme and the required template file exist.”

I get this with any theme I select. The desktop version still runs, but on mobile I get the above message.

Any ideas?
