Signature will not let users sign on paged form

Hi all,

I’m working on a website that is using the Gravity Forms Signature Add-On. They have a 4-page admission form that has a signature field at the end of the form. The form in question is at

I’ve disabled cache plugins, made an exception for every single gravity form file to not be cache’d. I’ve uninstalled and re-installed the plugins. I’ve moved areas where the signature field is. The signature field allows a user to sign if they’re logged into the site while live. The field also allows a user to sign when I have the site pulled down locally, either logged in or not logged in. The only time the field does not work is on the live site when a user is not logged in.

We’re using Gravity Forms v2.9.8, Gravity Forms Signature Add-On 4.8.0, PHP 7.4.

On the live site, I do receive a couple of JS errors in the console when not logged in going through the form that I don’t receive when logged in. First one is:

scripts-theme.min.js?ver=4.8.0:1 Uncaught (in promise) TypeError: Cannot read properties of null (reading ‘44’)

Second one is:

gform-pagination.91f86e988d8ec76485f9.min.js:1 Uncaught (in promise) TypeError: Cannot read properties of null (reading ‘type’)

Any help would be greatly appreciated!

For what it’s worth, we added a different plug-in for now and that works. Ideally we would like to use the official GF Signature Add-On.
