Safari issue

Hi There,

I’ve got TML set up with custom templates for the forms. It worked like a charm. Until I recently discovered that it isn’t responding to submitting the registration form in Safari.

Everything is okay in Firefox and IE. But when clicking the ‘submit’ button in Safari on my registration page, the page just reloads without doing anything with the provided data or giving errors for non-submitted data. It happens in Safari on my Mac as well on iPhone.

I don’t have a real clue, since it’s specific to one browser, where to look for the solution/problem.

I really hope one of you guys can give a hint or have any idea!

The form is live at Topografie in de Klas
