An old admin got the password of current one and opped everyone, they destroyed whatever they want and they gived themselve whatever they want :/ I need to: - mass deop everyone; - how to check who are ops? - rollback the world 2 hours ago - structures and inventories; Haven't coppied the world folder for days, even 24 hours rollback will be great compared to what is now :/ Please - give me ideas how to fix this huge issue I have :/ Plugins I use: Permissions, big brother, lockete; Others I supose will not have any infulence of the situation. The solution I got at the moment is: Ban every opped youser and just dont let him play anymore. BB Rollback every opped user for 24 hours. Anyone with better idea :/?
