Shader not loading in end

Whenever entering the end dimension the shader doesn't load and the game gives me a message saying the shaderpack failed to load. I am using the Bliss Shader. Copying the info gives me this error message: crumbling.vsh: crumbling.vsh: 0(124) : error C5052: gl_FragCoord is not accessible in this profile 0(132) : error C5052: gl_FragData is not accessible in this profile 0(132) : error C7533: global variable gl_FragData is deprecated after version 120 0(133) : error C5052: gl_FragData is not accessible in this profile 0(142) : error C5052: gl_FragData is not accessible in this profile 0(143) : error C5052: gl_FragData is not accessible in this profile 0(144) : error C5052: gl_FragData is not accessible in this profile This problem is only occurs in the end. The nether and overworld work fine.
