Are you using Chrome?
Webflow uses https - which means that there is a requirement to have to allow unsafe scripts.
Chrome has suddenly removed the “warning/option” to allow “unsafe scripts”.
Therefore any JS scripts will no longer function when publishing from Webflow using chrome.
If you use IE or upload to a seperate site away from Webflow - then I suspect it will work.
