We are using Oceanic Premium, with Woo Commerce installed 2.4.13 (if that has any relevance) but when testing on any mobile device the top menu doesn’t work, any ideas.
I see your site is giving some JavaScript errors which I think could be the source of the problem:
Uncaught TypeError: Cannot set property ‘prototype’ of undefined
Uncaught TypeError: Cannot read property ‘prototype’ of undefined
Uncaught ReferenceError: popupe is not defined
Uncaught TypeError: FLA.Map is not a function
Check those out and let me know if it doesn’t solve the issue!
