title: Magento admin css missing due to using file system path
body: <p>I was unable to install a module using Magento Connect, getting a <code>Connection Error try again later</code> error. Following the instructions of the module developer I attempted to fix permissions in the document root with:</p>
  
  <pre><code>find . -type f -exec chmod 644 {} \;
  find . -type d -exec chmod 755 {} \;
  chmod o+w var var/.htaccess app/etc
  chmod 550 mage
  chmod -R o+w media
  </code></pre>
  
  <p>It still didn't work so I ended up installing the module manually. I then logged into the admin backend and Magento was trying serve CSS files using the system file paths instead of URLs like so:</p>
  
  <pre><code>&lt;link rel="stylesheet" type="text/css" href="/home/user/public_html/js/calendar/calendar-win2k-1.css" /&gt;
  &lt;link rel="stylesheet" type="text/css" href="/home/user/public_html/skin/adminhtml/default/default/reset.css" media="all" /&gt;
  &lt;link rel="stylesheet" type="text/css" href="/home/user/public_html/skin/adminhtml/default/default/boxes.css" media="all" /&gt;
  &lt;link rel="stylesheet" type="text/css" href="/home/user/public_html/skin/adminhtml/default/default/custom.css" media="all" /&gt;
  &lt;link rel="stylesheet" type="text/css" href="/home/user/public_html/skin/adminhtml/default/default/xmlconnect/boxes.css" media="all" /&gt;
  &lt;link rel="stylesheet" type="text/css" href="/home/user/public_html/skin/adminhtml/default/default/print.css" media="print" /&gt;
  &lt;link rel="stylesheet" type="text/css" href="/home/user/public_html/skin/adminhtml/default/default/menu.css" media="screen, projection" /&gt;
  </code></pre>
  
  <p>I immediately removed the extension and tried to match the perms from another server with a working Magento to no avail. I have also:</p>
  
  <ul>
  <li>Cleared local, APC, and Magento caches</li>
  <li>Looked in error logs (logging is enabled)</li>
  <li>double-checked proper values of web/unsecure/base_url and web/secure/base_url in the DB</li>
  <li>Rebooted, 3 times ;)</li>
  </ul>
  
  <p>Minify is not being used. Merge CSS files are enabled, however I cannot figure out how to disable without the admin interface (save and navigation isn't working, even when I replace the correct values with Firebug). Any ideas would be greatly appreciated!</p>
