Croccante Theme: Menu doesn’t show

I have gone through all the help documents & forums. One day my site menu disappeared. All that is left is the “Home” button at the top right corner which takes visitors to the home page.

I have already checked:
– The latest plugin-ins for compatibility
– Menu is created & set to “Primary” location
– Widgets (created a new menu push sidebar with no change)
– Settings: Reading … all info there is correct

I’m sure I’ve tried other things, but at this point have lost count. Any ideas?
