hi
Checked.. but I see menu, but after that I got a message that my theme is not support menu.
Also customize >> navigation is not there and I think that’s the problem.
the site I use for testing your theme is: https://www.martijnhogendorf.eu/franklin
the one I want to build for final website is: voornopgaatdezonop.nl
on this website you will see the home and products at the site, but this is a widget menu.
deleting and re-installing your thema didn’t help.
it looks like there is some thing in the cache??
