Form is displaying blank when it is embedded using Feedback button on my WordPress webpage

I just installed JotForm Feedback button and created a form from a template. It is at: https://form.jotform.com/62606619062152

But when you go to my webpage, the form display is blank:

How do I fix that?

That makes sense why it doesn't work, but your answer does not fit my situation. I am using the Wordpress plugin.

I was able to use the Wordpress editor to modify the actual plugin PHP code, to change from HTTP to HTTPS, and that seems to have fixed it. Thank you for your help!

Great! Glad to see that the issue is now resolved for you. Please do not hesitate to get back to us if you need any further assistance. We will be happy to help. 

Thank you for using JotForm!
