Essentials SignInteract Error

I don't know what triggers this, probably interacting with a sign.... but it happens sometimes when I interact with a sign, and sometimes it doesn't. I don't know how to fix it, maybe you do. Please help, Thanks. =D

Looks like your using a too old/new version of the plugin. From the error it suggests that the plugin is the incorrect version as they method is not in your craftbukkit/spigot version. Please try to update your plugin's version

What Version is this Essentials?
https://hub.spigotmc.org/jenkins/job/Spigot-Essentials/

My Server is 1.8 and I'm using that essentials

 

Well, looking in the plugin (decompressed) it's 1.8.1 so try a earlier version of the plugin

 

current version of Spigot Essentials works fine on 1.8
