Wie schon gesagt, die Zeilen oben drüber wären auch noch interessant. Ob da jetzt der Grund steht oder nur etwas, dass (mir) bei der Suche hilft ist ziemlich egal.

Ich kann trotzdem ja mal ein paar Fragen stellen:
1. Irgendetwas am Server geändert und seit dem gibt es die Probleme?
Bukkit- oder Plugin-Update. Neues Plugin, ... etc.
2. Irgendwelche Mods im Server?
3. Serverversion? Ich möchte soetwas haben: "git-Bukkit-1.3.2-R2.0-b2396jnks" (die Zahlen werden bei dir wahrscheinlich anders aussehen. Das ganze ist in der Zeile "This server is running CraftBukkit version ....")

Edit:
Gut, da habe ich zulange geschrieben der Fehler ist ja schon vollständig.

Die Ursache für dein Problem ist ein Plugin. Wenn ich es richtig sehe heißt es "SpamGuard". Das Problem wird sich nur durch das Entfernen des Plugins oder einem Update beheben lassen. Wobei das Update diesen fehler auch wieder beinhalten kann, was aber unwahrscheinlich ist.

Ich danke dir vielmals! :)
