class does not name a type even though it is defined

miror (4)
Hello, when im trying to build my project im getting "<class name> does not name a type" (on the line "DataBase db;//an object of class DataBase" of Menu.h)
However, in file Menu.cpp (that includes Menu.h), all the functions and objects related to database do work.
I've tried rebuilding.

my code looks like this:

Menu.h

circular includes. There is no reason for Database.h to #include "Menu.h"
