WHat I find very confusing is that you need to turn OFF 'mobile theme' with Oxygen theme in order to have a good view on your mobile. Isn't that strange?
If you turn ON mobile, you don't see the showcase template anymore. You will only get an empty menu and you only see the page which you needed to appoint as the showcase page in static view.
THis is a real bug I believe. Please address this to the theme developpers.
The blog I need help with is didieschackman.wordpress.com.
