Solved
Does anyone know what could be causing this form to stay on the page upon submission rather than redirecting to our thank you page?
Currently switching hosting platforms and trying to test forms on the new dev website
A handful of forms are not redirecting
Forms are working on other published websites
WebOps manager suspects it's because dev website doesn't have an SSL certificate - could this cause the issue?
Other forms ARE working on the dev site
Form URL: http://procurifydev.wpengine.com/get-started/
Relevant Code:
The page includes a Marketo form embedded in the hero section:
html
The page is a standard WordPress template with Marketo form integration and Clearbit enrichment. The form loads properly but doesn't redirect after submission as expected.

Redirected just fine for me.
Redirecting from a plaintext site (non-SSL) to an SSL site — as is the case here — isn’t a problem. The other way around is blocked by browsers.
Still, it’s highly recommended that your dev site accurately mirror the security of your prod site!
P.S. You don’t need to do this:

Simply append the Email Address to the Thank You URL instead, seems unnecessarily fragile to expect them to type the same thing.
