You sir, are a gentleman and a scholar!
It works if the permalinks are in default mode i.e.
yourdomain.com/?p=123
but not in month and name mode i.e.
yourdomain.com/index.php/2008/06/sample-post/
which is a custom structure of:
/index.php/%year%/%monthnum%/%postname%/
Not very SEO friendly but at least it works….
Many thanks!
