  <p>But nothing works
  I have tried to comment out the code lines in  </p>
  
  <pre><code>app/code/core/Mage/Core/Model/Session/Abstract/Varien.php.
  </code></pre>
  
  <p>and nothing!</p>
  
  <p>And I changed the <code>core_config_data</code> <code>web/unsecure/base_ur</code>l and <code>web/secure/base_url</code>.</p>
  
  <p>I am running out of ideas,
  Thank you for any help!</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>I checked the cookies on the old server, and when on the login page i get an <code>adminhtml</code> cookie, but not on the new i get an <code>hz_amChecked</code> cookie.</p>
  
  <p><strong>EDIT 2:</strong></p>
  
  <p>The new server is on siteground, maybe something I am missing on the settings there
  I tried to put a <code>die()</code> in <code>app/code/core/Mage/Core/Model/Session/Abstract/Varien.php</code> but nothing happens.</p>
