Webflow is blocking onClick Events
In some cases, you can experience that Webflow's templates are set up in such a way that it blocks onClick events preventing the pop-up from closing when clicking the buttons.
This is the fix
function replaceOnClick() { $('*').each(function() { $(this).attr('onclick', $(this).attr('onclick'));});}$(window).bind("load", function () { replaceOnClick();});
