We are having an issue where a few forms in our application have started throwing the following error: 

Error Details
Error occurred while executing on load script.

This also affects forms on a separate application that was a prior instance of the current application and hasn't received any development updates for a few months. 

I've removed all On Load scripts and still receive the error. I've sent support an email and added edit access, but have not gotten a response. This is an urgent issue as business continues 12/26/2017 and this stops the business from properly functioning. 

I'm available to answer any questions as needed.
