Thank you!
I overtook Jetpack problem by removing it (and adding facebook/twitter widgets by inserting some code i found on facebook/twitter pages)
Now Oxygen is working quite well on mobile, but I would like to
- HAVE THE PRIMARY WIDGET BAR after the posts, before the secondary widget
- DISPLAY THE CONTENT OF THE FIRST MENU
- RENAME THE SECOND MENU (from Menu to Whatever)
Is this possible?
