Hello
I’ve had the same issue with my website, however i have been able to remove the ‘spinning’ menu, but now my responsive menu won’t display.
It seems there is an issue with the php for the nav menu on the new wordpress, please can you provide an update to the theme rather than dealing with individual queries?
I don’t want to give you access to my website for you to fix it, I want you to tell me what was broken so I can fix it.
