Cannot get editor widgets while creating projects

As in the subject, when creating, o modifying a project, a new windows starts, but I only get an empty pane, the widgets are not loaded.

I use Ubuntu 14.04 LTS, Chromium and installed Xerte on an Aruba server using Apache/PHP/MySQL.

Attached to this post is a screenshot of what I get.

Thank for your attention,
Ric

Could you please look in the console of your browser if there are any error?

In Chrome, press F12 when you get this screen, then refresh (F5), then look at messages in the console tab
