安全错误。 该怎么办

I have a problem with responsive file manager for tinymce, files easy upload and download. But when i try to add my file in edit space of my editor i have an error. Didnt know what to do with it.

That error i recive in ChromeBrowser

Uncaught SecurityError: Blocked a frame with origin "http://actamedical.loc"
from accessing a frame with origin "http://actamedical.loc". The frame being
accessed set "document.domain" to "actamedical.loc", but the frame requesting
access did not. Both must set "document.domain" to the same value to allow access. 

That in firefox.
