Menu doesn't work on mobile version

Hi,
The menu displays fine on the desktop version but when I test it on my mobile device all I see are the three lines and when I try to open the menu nothing happens. I had someone who is good with WP look at it and they said it’s an issue with the theme.

I should specify that the theme is the free illdy and my website is http://thenomadtoolkit.com/

Hello there,

I hope you are doing well today.

Please try disabling any third party plugins that were not bundled with the theme as one of them may be causing a conflict with the mobile menu.

Best Regards,
Support

I tried deactivating the plugins one by one and that didn’t change anything.

I’ve deactivated all plugins on my site and the issue still persists. On the desktop when i switch to the mobile version the menu button doesn’t work. The same as when I try it on my mobile device.

Hey there

Is this problem already fixed?
i just checked it on chrome and firefox mobile menu works just fine for me, can you verify it once again?
