Hello smart people! I am getting an error with most of the plugins I try to install. World Edit and EssentialsX being the two most important. [15:25:04 ERROR]: Could not load 'plugins/worldedit-bukkit-6.1.3.jar' in folder 'plugins' org.bukkit.plugin.InvalidPluginException: java.lang.UnsupportedClassVersionError: com/sk89q/worldedit/bukkit/WorldEditPlugin : Unsupported major.minor version 51.0 This is the error message for all the plugins not working. Here is the full log when I start up my server: http://pastebin.com/TbPEb1qq I am using Java 8, the newest version of World Edit, and PermissionsX, and running a 1.10.2 Spigot Server.
