Ich versuche, ein Forum mit PHP und Html zu machen, ich fange immer noch an, damit ich auf Stapelüberlauf gehen kann, um Antworten zu erhalten. Wie auch immer, das funktionierte früher gut, aber jetzt habe ich diesen Fehler. Ich habe keine Ahnung, wie ich es beheben kann und es ist wahrscheinlich nur eine kleine Sache.SQLSTATE [23000]: Verletzung Integritätsbedingung: 1048 Spalte 'Nachricht' kann nicht null sein
