So i have seen alot of people have been having trouble installing essentials 1.8 how it either dont work or they lose all there files well ill tell/show you the eaiest way to upgrade essentials to 1.8 and still keep your files

Okay so you want to upgrade essentials to 1.8 first of you will need to go into your essentials config copy and paste the whole config and place it in a word document or a word pad and save it onto your desktop you will need this later then you will need to delete all of essentials folders and plugins. Go to this website for 1.8 essentials https://hub.spigotmc.org/jenkins/job/Spigot-Essentials/ download the ones you need if you are running a kitpvp server or factions or any server i dont reccomend anti_build unless you know how to config/bypass it , go ahead and download and install all the plugins and reload/restart your server , if the plugins are green when typing /pl or /plugin you are good to go if not check your console.
Now all you have to do to get your files back is simply delete the new config and paste the old one you saved onto your desktop into the config and there you go essentials 1.8 with all your config,
I Hope you found this tutorial helpfull and if you did be sure to leave a diamond thanks
