Solved Server won't start up!

Hello there,
Suddenly, for some reason which is unknown to me, my server doesn't seem to want to start up. I am running spigot 1.7.10 and I get this error:
(Please note, the console reads from top to bottom.)

I don't know if any of you folks know how to fix this but I though I should ask anyway.
Thanks,

One of your .json files is broken. Did you edit any of them? You can't just put player names in them anymore (thanks, Jeb!). You may have to move them out of your server folder one by one until you find the broken one.

 

@Bobcat00 I think I may know the problem. I couldn't unban players in game so I just removed them from the banned-players.json file. I guess that is the problem then. Thanks, I will try now.

EDIT: Yes! Thanks!
