Form gets stuck on processing and complains of a pop up window

The website for this form is not https:

When I test /submit this form using this link (not on the website) directly via the form link, a pop up warns of non secure connection:

When I test my form via Jotform "preview" it gets stuck on processing.

When I add the form to Wordpress via Jotforms Embed plugin, same thing - it gets stuck  PLUS it gives a warning about pop up window.

The page is in preview mode so I don't have a link for you.

I was trying to replace a Gravity form...

The Send Post is enabled in the form, but I don't think you are really using this to submit your form data to a third party program. If this is correct, then no need to keep it enabled.

The page gets stuck because of the popup permission. Popups are blocked by default in all major browsers so in this case, you need to allow popups for Jotform in order to submit the form. 

Ok that worked and I didn't change a thing in my browser setting.

Thanks
