How can I go back in and edit submission?

This problem I've asked a couple of times,but when I go back and edit the submission,it times out and I get bad gateway? Help!

I believe this is the same question to your thread here https://www.jotform.com/answers/818797-My-form-isn-t-allowing-people-to-edit-submissions-

I have responded to the original thread already. Please use that thread instead for your follow up mssage/question.

I will close this one.

Thanks.
