<p>File uploading seems to be disabled on your server.</p>

<p>Moodle can still be installed, but without this ability, you will not be able 
   to upload course files or new user profile images.</p>

<p>To enable file uploading you (or your system administrator) will need to 
   edit the main php.ini file on your system and change the setting for 
   <b>file_uploads</b> to '1'.</p>
