Cant load server

Do you mean downloading the world file, delete the world(server wise) and then uploading the world file again?

Because if so i have already done it

oh so just deleting the world?

Well that worked, i can now join my world, but how do i but back the world i wanted to play in, aka the one with the command blocks?

Oh so its gone forever?

Well, i guess i have to restart. Thank you for your help
