All of my custom Debug logs are not allowing me to compile my code

This is what works for me. Hopefully it will help you as well.

In your project header file (MyProject.h), add the following:

DECLARE_LOG_CATEGORY_EXTERN(LogMyGame, Warning, All);

In your project cpp file (MyProject.cpp), add the following:

DEFINE_LOG_CATEGORY(LogMyGame);

Hope this helps.
