My site is already running on the new v2 system, the time has come to after a long time that I start make the theme for v2 system.
After several failed attempts to update my page to the new V2 system, the update succeeded.
A theme has login page (index page) and the other pages fix width: 1000px.
A theme has the fullpage slider on the main page (index pagel) and the other pages fix width: 1000px.
