My Dashboard is always empty and I can't add widgets

What's up? I added a lot of widgets in my dashboard (I work hard on that) and then my dashboard just got cleaned. There's nothing. Besides, I can't add widgets now.

Where does it happen? Dashboard

What browser extensions are installed? Adblock and Ghostery. I read those extensions could be a the problem, I disabled them, but still I have this problem.
