Hi dear,
I already followed this document before and I did again now to be sure that I followed exactly like the documentation. Really, I don’t know how to setup a Menu different from that document.
Take a look what I have checked:
1- When I access the “Appearence –> Customize” there is a option on left bottom to select/simulate the size of the screen. By the simulator, the menu is appearing for the 3 options.
2- When the “Site’s title” and “Description” is “Meu WordPress” and “Só mais um site WordPress”, the Menu just appears by the 2 first size of the screen.
Ps.: My installation was done in Portuguse language.
I hope you can continue help me.
Thank you very much.
