Visual Composer or Frontend not working with WordPress 4.5.2

Hi,

Yesterday i updated my WordPress version from 4.1.11 to 4.5.2. Today i tried to edit some of the pages of my website but either i try by the visual composer mode or frontend mode, both aren’t working at all.
Can you please help me to solve this issue? Because i need to add some information and i can’t at this moment because of this problem.
Mi Highend theme version is 1.7.

Thanks!
