I have been trying to use command blocks lately i paid for a basic empire but still no luck im just kicked when i hit done Could i please have some help?
Create a support ticket, do /gamerule CommandblockOutput true, or try another method other than command blocks.
My whole world runs on command blocks. They work fine for me! Except essentials commands and /weather clear.
You just need to /op yourself, it is stupid but opped people are in a different group to administrators in game, so only opped people can, just do /op <your IGN> and it will work fine.
Users running a version 1.8 client often experience issues with being kicked from the game. Make sure you are running a 1.7 client (I believe 1.7.4 - 1.7.10 should work fine).
The command /gamerule commandBlockOutput true does not effect command blocks. It only stops them from saying in chat stuff like, "Teleported CatMasterplaysmc to 10 75 400".
