How Do I Test My Forms?
We strongly recommend using Google Chrome's Incognito mode or Safari/Firefox's Private Browsing mode to test the forms on your website if they aren't showing up in normal mode. This makes you appear as a new user to the website. It is more effective than clearing your cache and removing your cookies.
If you are having issues with testing your forms, that is most likely why.
This tutorial applies to popup / popover, scroll box and top bar forms.
