Why is my jotform not opening in Internet explorer?

Every time I click through on internet explorer it gives the error seen below:

In which Internet explorer did you test your form? I checked in Edge and Internet explorer 11 and I couldn't replicate this issue?

Also, did you test the form directly or you are redirecting from some other URL?

The test was done from Internet explorer 11 (and a co-worker also tried from IE8) both came up with the same issue. 

The form is linked through an image off of the page URL given in my first post. We've done this before and never had issues with IE either so I'm unsure of what the exact issue it. 

Thank you for additional information.

I tested by following those steps in Edge and I was not able to replicate this issue. But I see the potential problem and that is that the website from which you're redirecting your users is non-secure:

And then the form is secured so that's why the warning from IE (most probably). This should be fixed if you switch the SSL on your website.

If you have any further questions please let us know.

Thank you!
