I can not enable the buttons on the navigation manager
 

Hello, yesterday I downloaded the latest version, the beta 14. HLa I've installed and there is a serious problem.
I can not turn ON the navigation bar to the home and edit, add pages etc.
Manager AdminCP Page New Page Edit Page Header Footer Navigation Bar
This is the menu that does not leave.
I give the button to activate it and does nothing, always OFF. With the beta 13 works perfectly, I tried to upgrade from 13 to 14 and gives the same problem.
This happens to me on a server Debian, Ubuntu works perfectly local.
I've done several facilities have regenerated the style and always the same.


That is what can be wrong?


Thank you.
