Constructor for object "$.pkp.controllers.PageHandler" not found! OJS 3.3.0.8

Description of issue or problem I’m having:
When i want to go to /index.php/index/admin the page loading break and i have an error message like this : “Uncaught Error: Constructor for object “$.pkp.controllers.PageHandler” not found!” in console

Steps I took leading up to the issue:

What I tried to resolve the issue: I thought the problem was with the proxy, but when I point to the index.php / index / admin / systemInfo page I do get the PKP version info. I try to change proxy parameters but nothing better.

Application Version - e.g., OJS 3.1.2:
OJS 3.3.0.8
force_ssl on
force_ssl_login on
proxy activated
