Hey so I'm not a noob before you say "look in server.properties" i have and still not working. The basis of my problem is the fact that I CAN hit players but players can't hit me what i don't understand is why players can hit each other but no me lmao. I have tried server.properties , mv, regions etc but with no luck. ~ Gears
Yes, players can pvp fine just me or admins can't hit each other OR players can't hit us but we can hit players and players can pvp each other
You might have some kind of permission to make you exempt from being hit. This is why you don't give the literal "*" permission node to yourself. You'll have to find out which plugin is causing it. You could disable plugin by plugin until it's fixed.
Sounds like your staff has invincible set or they are in creative mode. Could also be a plugin with a permission as nano said.
