I get a blank screen when I click Edit Form option in my forms page

I have 2 different JotForm accounts & both are doing the same thing. When I tick an existing form from my list & click on Edit Form, the new window that opens presents a completely blank screen. Therefore I can't edit it.

This is probably related to your browser cookies for Jotform since I was able to edit your form. Please try clearing this in your browser, do the same with your browser's cache. This should fix it. If not, please update us here. 

I would also suggest using multiple browsers. One browser for your current account and one for the other.
