Anyone else get crashing after the v3.0.3 gravity plugin update?
I also cannot submit a support request on the gravity support page, get these errors:
scripts-theme.min.js?ver=301fdc9aa6144168f3b854c4c2c8f6d3:1 Gravity Forms: Aborting submission. Another submission is already in progress for form #135.

Hi Dave. We don’t have any other reports of trouble with the support form, but you can submit this form without logging in, and let us know you’re having trouble with the technical support form:
https://www.gravityforms.com/open-support-ticket/general/#gform_137
This was resolved via support ticket. It was related to the following changelog entry from the 3.0 release.
- Updated form buttons to use
<button>elements instead of<input>elements for better accessibility and styling flexibility. It is no longer necessary to use thegform_submit_buttonfilter to change the submit input into a button, and use of that filter might cause unexpected issues.
The site was using DOMDocument with the gform_submit_button filter to change the button text on click. With the change to button elements, and the code specifically targeting the old input element, it couldn’t get the button to modify it.
The new button text is hidden on click and replaced by the new spinner, so the code snippet is no longer required.
