This happens when i have PoreRT 1.10 installed, I get only a small error in console like 'Name changed from Error404_Found to [Admin] Error404: during chat event!'.
If i try to use PoreRT 1.11 the chat works, but i get a BIG error in the console. (Check logs)

This is the log when i have PoreRT 1.10
Latest PoreRT1.10.txt

This is the FML log when i have PoreRT 1.10
FML Latest PoreRT1.10.txt

This is the log when i have PoreRT 1.11
Latest PoreRT1.11.txt

This is the FML log when i have PoreRT 1.11
FML Latest PoreRT1.11.txt

The problem with PoreRT 1.11 is that i get some FML event errors like 'FMLServerAboutToStartEvent' or 'FMLServerStartingEvent'

"Forge Mod Loader version 12.18.3.2202 for Minecraft 1.10.2 loading" I don't support 1.10...
