To deactivate SSL submissions just use http://form.jotform.com instead of https://secure.jotform.com
So when embedding a form URL it should be like this
Just uncheck the Secure form checkbox to not receive an SSL submission.
This is not an open for embedding on Google Sites?
We can embed non-ssl form to the Google Site using third party Embed Gadget. However, it seems that Google force SSL connection to the Google Sites, so it is better to use SSL forms, otherwise some users will not see the form due to blocked "unsecure content" on the page.
If you are referring to something else, please open a new thread. Thank you.
