menu not visible

For some reason the main menu is no longer visible on the main/home page:
mywollybear.be/
It was visible in the beginning so I must have done something wrong...
But when I insert a /submenu-name than you can see it
mywollybear.be/bernersennen-honden/onze-berners

What did I do wrong? Any idea?

 

Solved!
I should have searched myself a bit longer

Hello,

Your menu lost its styling. I am attaching the default settings for the menu for the Dogs template.
