Added SSL to site - Some form don't work now - ERR_INSECURE_RESPONSE

Hi,

I added SSL to the whole of my website a few days ago.  Now, some of the forms on my website don't work and I'm not sure why.  I'm using Chrom and checking the Javascropt console is giving this error message - Failed to load resource: net::ERR_INSECURE_RESPONSE.

The forms that aren't working are;

1)

Form: https://form.jotformpro.com/jsform/40413072946956

Form: https://form.jotformpro.com/jsform/40426370157955

However, some forms are working ok, such as;

1) 

Page: https://productlondon.com/audio-mastering/pay

Form: https://secure.jotformeu.com/jsform/40102614762343

The forms are showing ok when I'm logged into my Wordpress Admin page but when logged out or checking on another computer, the form does not show.

Thanks for your reply. I might be missing something really obvious but where can I see the code with the paragraph tags and breaks (<p></p>, </b></br>).  I'm not seeing the tags in either the visual or text tabs of Wordpress.

That hasn't worked either.  I can see the form ok whilst logged into Wordpress but as soon as I log out, the form disappears.  It's the same on my Macbook or my PC and with different browsers.  I've tried clearing the cache but that hasn't worked.

Also, I don't understand why this is only happening for some forms when I'm following the same process?

Ok, got it working.  It was to with a caching program I was using (Quick Cache).  I deleted and installed WP Super Cache.  Deleted the cache with WP Super Cache and the forms are showing ok now.

Thanks for helping and hopefully someone else will find this useful in the future.
