Ontopic: voor wie het ook wil gebruiken: Textarea's die zijn veranderd in een 'Codepress-editor' geven geen POST waarde meer mee als je op submit drukt. Je kunt de content dus niet zomaar opslaan. Ik heb dit opgelost door de submit button van mijn edit-formulier een onclick mee te geven:
<input onclick="namevanjetextarea.toggleEditor()" type="submit" value="Save">
Hij veranderd hierdoor de Codepress-editor eerst in een normale textarea en verzend pas daarna het formulier.
