Anfängerfrage: Ich versuche aufgrund des Beispiels auf wordpress.org eine Options Page für mein Plugin zu realisieren - klappt auch mit den "Select" Feldern... die Optionsfelder "Diaspora" und "Postpone" werden korrekt behandelt. Aber für ein simples Textfeld ("localecode") bekomme ich es (noch) nicht hin. Was mache ich falsch:
