Need a space between - and player

 

1 more thing, I keep on getting errors saying : [SEVERE] Could not pass event PluginEnableEvent to Essentials v2.9.5 org.bukkit.event.EventException. Got any idea on how to fix that?

 

Really not sure, seems like a rare error, try removing using stock configs (if changed) other than that, try an older version ?

 

i get the same damn error. please help if you can.
