Help determine essentials version and if it is wrong version.

Here is a pastebin of my server's startup process.

I can't seem to figure out which version of essentials I am using. My host is fragnet so they helped me setup some of the essentials portion.

How can I figure out the essentials version and it is a good version for my current spigot version?

I am receiving the same errors listed in the thread linked below, but there was no clear answer except maybe switching the essentials version.

I ran what you said and I got this message.

CONSOLE: [INFO] /<command> <reload/debug>

I didn't get an essentials version.

What can I do now at this point?
