Please note that if you have a HTTPS (secure website) then you must use secure form as well because you are loading resources from different locations.
If they are not secured, then they would not be working correctly and a warning triangle would be shown to you and the jotform would not be shown.
Once both are secure, the secure icon should be shown to your visitors.
