I just moved my wordpress site from one server to another. Moved all the files, moved the database, reconnected everything and it (almost) works perfectly fine.

Except for this: The links to the different posts are broken (I only get 404s), eventhough the individual posts exist in the wp_posts table in the db and seem just fine. I think this might be related to a URL change, but I didn't change my domain, nor did I change any of the directories.

For example: / loads fine and displays the correct content, but when I click the e.g. background link it trys to load .php/background/ which results in a 404, eventhough I can see and edit the page background in the admin area.

What did I do wrong here? On the old server it loaded and displayed the correct content just fine.
