Hello, aliflo here. See the bold stuff for relevant information. Well, recently I've been helping a friend.. uhhh.. make the transition from 1.7.5 to 1.8 (he's scared of losing craftbukkit and crap like that) and so on a 'scouting mission' I tried to set up a Spigot server. I set it up and to test the plugins, added Worldedit. Then I realised I should probably check essentials works and... well... Essentials didn't work. I downloaded it from here: https://hub.spigotmc.org/jenkins/job/Spigot-Essentials/ and pastes these files into my Plugins folder: Essentials: Antibuild Chat GeoIP Protect Spawn and regular Essentials. None of them were the 'original' files. Upon running the server I was greeted with the error message shown in the attached PDF. I dismissed it and went on the server - it worked - and tested worldedit, which still worked, and then tested essentials. When I typed in a command, such as /hat or /gm, nothing happened. I mean nothing at all. THe same with just the regular essentials file on its own. If anyone knows how to 'fix' this, then I would greatly appreciate it. In the console, it said I issued a command but nothing happened. PLEASE HELP!
