I've got this piece of custom code that seems to be installed correctly, but something is blocking it from loading.
Here's the live page: http://salesographer.webflow.io/webinars/drip
Click on the REGISTER button and try to register. You'll see it just loads and loads and loads.
Reached out to WebinarJam's support and got "yeah, it's installed correctly. We can't help you."
Getting a console error about mixed content
