My server crashes, please help

When I start my server it is fine and goes into queue and the status says loading. When the status reaches starting it stays as starting for about 4 minutes and then the server stops. While it said starting I checked the console and it says crash report has been saved to Aternos/servers/SuperJay360/ so on. I can't view the crash report and fix it and I may need help from the Aternos admins. Please help!

I even tried a new account and a completely new server and it still came up with the same crash/error.

I think Aternos is broken. It is definitely not the fault of my internet.
Admins please fix this problem!!

_{FaZeDarkStar I am using spigotMC 1.8.3 with two 1.8.1 plugins: WorldEdit and Essentials.}
Shouldn't all 1.8 plugins/versions work on any 1.8 version (1.8.3 plugin but 1.8.9 SpigotMC) <- Example

Isthere a chance I can download the world and upload it or is that world gone?
I really hope it isn't because I was using that world to do a survival server with friends.

Thanks for helping me!
