Menue not working

Hi,

Menue does not work when viewing page in a mobile or using a tablet. I also checked your demo sites and none of them can show the menue, all I get is “undefined”. I have asked friends to check and also tested several of your themes and I get the same error. Due to Covid-19 I have not been able to work on my page so I do not know if this i s how it behaved from the beginning or this is due to an update on WordPress. Therefore a solution is not to renew the proversion untill the demo works properly.

I would appreciate some kind of guidance as to how getting it working or is the bundlepurchase a big misstake?
