Java.lang.NullPointerException on Spigot Server, HELP!

Hi,
So earlier today I was messing around with Per World Plugins in the config and then I restarted my server after adding the plugins I wanted in each world. After the restart sadly I could not join my server. I went to my console and found a crash report, here it is

I currently own a multicraft server using PaperSpigot 1.8.8, there is no option to use regular spigot except 1.9 and almost all of my plugins are still 1.8 so I dont want to go to 1.9. Please help!
