what happen ?

To enable "Developer mode" you have to click a bunch of times on the version number of "Content Manager" - "About" page. A message will pop asking if you want to enable "Developer mode". Confirm and then the buttons will appear.
If after that you don't see "Developer mode" in "Content Manager" - "General" page that means the mode is not enabled.
