Moodle v1.8.2+ Nightly Tarball on 20th Aug 2007 downloaded and installed on a BlueQuartz Appliance.
Install folder: http://www.domain.com/moodle
In the file moodle/install.php there are many references to
$INSTALL['wwwrootform'] . '/pix/docs.gif'
During Install, on the step that checks the PHP.INI settings, we get missing image place holders for docs.gif .
It is searching as http://www.domain.com/pix/docs.gif instead of http://www.domain.com/moodle/pix/docs.gif
As a temporary workaround I copied the pix folder to the docroot as well.
