so i started a new world to try out skript, whenever i try on the console to op myself it wont even reply , heres an image before i press enter and after i press enter

jxguar_ I see you are having issues with Essentials. Remove the Essentials plugin from your server in the File Manager then go to the Essentials website. Don't download the LATEST VERSION download STABLE RELEASE. Ill send you an image just encase you cant find it.

The player reset the server via console:/

Look up "useful plugins" on YouTube. 

If you don't have rollbacks there's nothing you can do to restore the server. 

If it was just griefing you might be able to rollback the chunks with a plugin though.
