A buddy runs a minecraft server with a citybuild world, a farm world, and a nether world. Everything worked great - until his brother unfurled around the configuration and could not say what he was doing.
Now nobody (not even the owner with asterisk rights!) At the spawns can change one block, but only about 25 blocks away. That's the way it is in all worlds.
On plugins are installed:
PlotSquared
EssentialsX
FastAsyncWorldEdit (we already disabled - no change)
WorldEdit (ditto)
PermissionsEx
Multiverse Core
NoCheatPlus (disable does not change)
ProtocolLib (ditto)
Vault (ditto)
SuperVanish (ditto)
SpawnTP
Except for PlotSquared, pex and spawntp, we have pretty much sent everything "out the door" and no change, and so I'm running out of ideas.
Oh yes, one more thing: on some servers you can see "smoke" if you mine something where you can't - not here. The change is instant reverted.
Now I hope for tips from you.
Sounds like spawn protection.
Already the spawn protection in the server.properties set to 0?
That's exactly what it was! Thank you, I have been looking for days stupid and stupid…
No problem.
Glad I could help!
