Cannot access submissions - I only get a grey screen

I go to forms, click on a form to highlight, click submissions and only the gray screen comes up with no data. I have been in before so I know it worked........what else can I try?

From what I understood you've tried to access submissions from more than one form. Have you tried more than one browser with the same result? Please try clearing your browser's cache to see if it solves. Let us know if the problem persists.
