The menu on our website on mobile is not working. It works fine on desktop, but the menu burger does nothing when clicking on it on a mobile device. The only recent CSS change I’ve made is because of the Kali contact form (https://forums.colorlib.com/t/kali-contact-form-disappears/27740/3). But I have to say that I don’t know if this is a new problem on our website, because I regularly check it only on desktop.
Our website is: https://www.ventilatietechniekbrabant.nl/
Thanks in advance!
