Builder: White screen when editing

Hello! 

When i am trying to edit my form i have just a white screen. How can i fix that? And it happens with every form that i created.

Can you provide us with your account username or account email address?

I have just been informed we were facing technical difficulties earlier today. That's why you were getting the white screen in the builder.

However, the problem has been resolved. It should be working normally now.
