The ezarchive template operator, which groups blog posts by month and is used in the eZ Website Interface (extra_info.tpl), creates a list of months which is in wrong order.

Example:
Posts in Dec 2006, Jan 2007, Feb 2007 - list will look like this:

• January 2007
• February 2007
• December 2006

but should be in this order:

• February 2007
• January 2007
• December 2006

This can be achieved by adding
ORDER BY YEAR DESC, MONTH DESC
to the SQL statement in ezarchive.php

Steps to reproduce

Look at the blogs at any site with eZ Website Interface demo data, like
