Your Java version. Forge isn't compatible with 1.8_20, either downgrade to 1.8_11 or 1.7_67



There is a bug in forge that wasn't apparent until they changed something in 1.8_20

I'm having a similar problem. When I open Minecraft with 1.7.10 forge, 3/4 of the screen in-game is just white.

THANKS SOOOOO MUCH!!!!! ITS WORKING NOW NOW I CSN FINAALLLLY PLAY FLANS MOD

Thanks, this helped a lot

i have the same problem except mine says this - BTW i have no mods installed so it cant be the mods doing it

the RED writing is the main thing it keeps saying! please fix

I'm sorry but I'm too poor to enjoy these delicacies you RICH people enjoy, still my game wont load, i downgraded my java to Java 7 and it still has the same error message. So PLEASE try and focus on the main issues, not the fact that I'm one of the MILLIONS of people who use a cracked launcher.
