Problem with Avia Layout Editor

Hey Guys,

I have a big problem with my pages.
I use different subdomains and in the last days I edited the subdomains a lot.
Today I wanted to edit one of the pages of my main domain, but when I open “pages”
and then select “edit” the Avia Layout Editor appears, but the area below,
where you drop your elements and content, is empty.
But when I visit the pages online my content is still there.
I seems that this area isnt loading right.
I tried it with all the pages of my main domain. Everywhere the same problem.
When I change to one of the subdomains everething is fine.
Could this be a problem with enfold?
I tried as well different Computers (Mac, Windows) and of Course several browsers.

To show you a little better what I mean, I added screenshots to the private content area below.
