When you fill the form and press sign up it stays stuck at “please wait”.
I have been searching mautic foruns and the solution is always found in the platform where the site was made or in a plugin installed, never on Mautic.
I think it has something to do with https or javascript.
I did not realized that you meant all scripts.
I already made the change and the form now works perfectly on desktop, although it does not load on ipad and iphone.
