Hello Tom
Thanks for the reply, I have not tried it yet because Uber menu support has created a guide for this problem, (https://sevenspark.com/docs/ubermenu-3/theme-integration/generatepress) they talk about putting A code in the child theme
My question is if with your solution when you update the theme will return the same problem
Before doing anything try in the future do not slow to happen
a million thanks
Jordi
