The following tutorial explains how to edit information displayed in footer area of Berry responsive theme on a Plone 4.2 website.
Berry Theme footer is subdivided into three parts: footer with Plone info (1) and theme credits (2) with standard Plone colophon (3).
All parts can be customized. To change standard Plone footer (1), go to Zope Management Interface -> portal_view_customizations -> plone.footer. Press Customize to enable editing of the current footer and change the text. Do not forget to save the changes when you finish.
To hide theme credits (2) and Plone colophon (3) you will need to add a special class to your ploneCustom.css.
#portal-colophon {
display: none;
}
