After upgrading to latest Publii and latest ProDoc theme, one of my sites got a broken menu.
My menu:
Menu item 1
Submenu
Submenu
Menu item 2
Submenu
Submenu
When i open the site i see first Menu1 part visible and Menu2 is empty
If i open a link from Menu2 i see Menu1 part is empty.
Before update it was visible – always.
I deleted a menu, save. Recreated and it is still broken
