Permalink bug appears in WordPress 2.6
There is a problem that has arisen with WordPress 2.6 - it seems to only really affect users that are using ‘index.php’ in their permalink structure (most likely hosted on Windows based servers - another good reason to move to a Linux server!). The bug is detailed over at http://trac.wordpress.org/ticket/7306.
This won’t affect users using permalinks without ‘index.php’ in the structure and I have personally upgraded a number of blogs and websites already upto 2.6 with no problems at all (all Linux, no ‘index.php’).
