Ich denke, daß es an dem Problem hier liegt: ![Unbenannt-1](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/4/4ee399642e2df3fd1b1855451b32ea5adb34df56.jpeg) Sobald ich den Rendering-Stil auf NEIN stelle und dann abspeichere, kommt die Fehlermeldung ERROR 500 Zum Testen hab ich ein Formular mit Renderig-Stil JA angelegt, da funktioniert es. Nun will ich aber mein eigenes CSS nutzen, und darum Rendering-Stil NEIN. Wer kann helfen? ---
