I have done the upgrade from 1.2.2 to 1.5. The Classic and Default themes work fine.
But mine doesnÂ´t. When I enter index.php or click on a categegory or use the seach just 'Sorry, no posts yet.' appears.
I followed this guidance to upgrade: http://www.tamba2.org.uk/wordpress/upgrade/upgrade_en.html (in English & German).
I cannot find my mistake. HereÂ´s the URL http://oerdec.com
I hope anyone has an idea,
