Essentials broken

Hi. Whenever I edit the essentials config, and I go into the game, everything works fine. But when I do /spawn, the server crashes. Using /warp won't work because players don't spawn there and also /setworldspawn won't help because I want new players to spawn somewhere else. Help please?

 

@timtower https://pastebin.com/aAv7hikk for full server log.

 

Here's my essentials config: https://pastebin.com/kf2HvhhE
I literally only changed "ops-name-color" under global.
Also, I got this crash log in my FTP. https://pastebin.com/tywWCq8D

Somebody told me to put the config in a "yaml parser" but they wouldn't help me further. (I have no idea what a yaml parser is.)

 

@timtower Nevermind! I resolved it by uploading a more stable and up-to-date version of essentials. Thanks for the help, anyways!
