Keystrokes no longer register

Today after cleaning my keyboard I plugged it in and noticed it's not responding to input.

Everything is situated correctly, the circuit board doesn't appear to be damaged and the wires inside aren't damaged either.

Placing the circuit sheet is pretty straightforward so I don't believe I made a mistake, but just to be on the safe side I snapped a couple of pictures.

I compared them to pictures I took before touching anything and it looks the same.

Well I never open my keyboard to such level, all I do is snap out the keys, clean the surface from left over food XD and put the keys back and it's like brand new.
