The error indicates to me that you do have two overloaded equality operators
in the String_mgr class, one that takes char * and another that takes const
char *.  I think you can do without the first one, because an overloaded
equality operator should never change the object, which means the argument
to the operator can always be const even if the variable on the right hand
side of the expression isn't.

I don't know the solution to the error, but an instructor taught always to
make non-member functions those overloaded operators which don't change the
object.
