title: Magento Core Config Data Cache
body: <p>I had some configuration data caching issues in my magento frontend that, </p>
  
  <ul>
  <li>I cannot get new shipping rates/get template path hints/ etc..  </li>
  <li><code>core_config_data</code> table get updated correctly and All backend data shown correcty.</li>
  </ul>
  
  <p>I tried "Flush Magento Cache" button, cleaning <code>&lt;DocumentRoot&gt;/tmp</code> directory,  cleaning <code>var/cache</code> directory</p>
  
  <p>(This issue is noticed 2 weeks before and I moved the site to new VPS a month before)</p>
  
  <p>Any ideas??</p>
