I just installed 2.4 following the Moodle documentation. The Moodle pages themselves load, but there are no images or themes. Admin links don't work...all the links become "edit.php?id=2&course=1". The login page says "Cookies must be enabled in your browser" even though cookies are enabled in all the browsers I've checked. $CFG->wwwroot is set to the correct address, which is the same address I'm using in my browsers to access through the Internet.
Moodle 2.4, nginx 1.3.8, PHP 5.4.6-1, MariaDB 5.5.28a
