I'm using <?php posts_nav_link(); ?> on the index page in WP 2.1.1
I start out with http://localhost/projects/Wordpress-test1/index.php
The 'Next Page >> link takes me to http://localhost/projects/Wordpress-test1/index.php/page/2/
Clicking on the << Previous Page takes me to
http://localhost/projects/Wordpress-test1/index.php/ which now has a trailing slash and a 404 error
Any ideas how to get round this?
