[Plone] Problème modification template colophon

Bonjour tout le monde,

Voilà, j'ai un soucis.

Je suis tout novice sous plone et zope, et je commence les templates.
Je voulais modifier le template de pieds de page colophon.pt.

Donc je vais dans portal_skins, plone_templates, et colophon.

Je clique sur customize, j'edite le code, que je remplace par un code tout simple.
Code:

1 2 3 4 5 6 7 8 9 10 <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en-US" lang="en-US" i18n:domain="plone"> <body> <div id="portal-footer" metal:define-macro="portal_footer" i18n:domain="plone"> Copyright © 2003 – <span tal:define="now modules/DateTime/DateTime" tal:content="now/year"/> by Société Géniale </div> </body> </html>
Enfin, je clique sur "Save Changes"

Le problème, quand j'actualise la page d'acceuil du site, j'ai une erreur :
