Shader in labymod black. What should I do?

I downloaded Labymod for Minecraft version 1.8.9 today, but after a while I tried to start shaders, which didn't work. I have already looked around on Youtube, but I didn't find anything useful there → "Sun & Moon" is activated. What could be the problem?

Does that happen with every shader you want to add? If so I would try it without Labymod if it works then reinstall labymod if it still doesn't work then I would update the graphics card drivers and reinstall Minecraft
