Hello, I recently installed optifine and sildur's vibrant shaders. When I did so my chests just won't open. If anyone knows how to fix I would be grateful. Thank you. Using latest forge and optifine.
1. You didn't specify what version of MC your using.
2. Most other post about this problem point to Forge. Try downgrading Forge.
3. Also try removing Optifine.

I've had the same problem some time ago. Just update optifine to the latest version.(or try other versions of optifine - it is definitely a reason of your problem)
