Using opengl and freetype2 together

I am trying to render fonts using freetype2 with GLFW. I rendered a 3D texture and some shapes. However, when I render font I see correct size but flat color instead of char texture. Interestingly If I bind another texture that acually renders. You can check it in fontRenderer.cpp

I am an amateur I, did it for hobby and I do not claim to be programmer. Most probably I am missing many things. That is why I added entire project to the github. I will be very glad if someone explains the prolem.

Note: I suspect that my shader’s color and texture operation can be wrong. You can check it in main.cpp
