I got an error at my 1.8-R0.1 Server

[xXSchrandXx]

Plugins: CleanroomGenerator, Clearlag, Essentials, EssentialsChat, iConemy, InfoboardReborn, Multiverse-Core, NametagEdit, PermissionsEx, Steel, TagAPI, TeleportSigns, TTT, Vault, worldedit, worldguard and my Plugin for Bungee.

It comes when I set the Spawnpoint for the players with "OK".

Your Spigot revision seems to be very old. Could you try to reproduce on the latest 1.8 build (git-e4d4710)?

[xXSchrandXx]

ok, thank you for the help

[caseif]

Were you able to reproduce the issue?

[xXSchrandXx]

It works now, no errors or bugs. Thank you

Do the spectator normaly spawn in gamemode 3?

Because user with '*' permissions getting in Gamemode 3 and the other in Gamemode 0.

[caseif]

Yes, they do. If they aren't, it's likely the result of a conflict with another plugin. Try systematically disabling them to see if you can determine which one.
