  "<a href="http://www.mywebsite.hu/en" rel="nofollow">http://www.mywebsite.hu/en</a>" and proceed registration the email successfully sent but when i click activation link like "<a href="http://www.mywebsite.hu/auth/activate/1/8ef760c2345d21654ae92f5a70017f5e" rel="nofollow">http://www.mywebsite.hu/auth/activate/1/8ef760c2345d21654ae92f5a70017f5e</a>" iam get the "The activation code you entered is incorrect or expired." error message.</p>
  
  <p>Then if i am clear the corresponding cookies to mywebsite.hu in the browser the activation is successfully complete. I dont know why...</p>
  
  <p>in codeigniter config.php</p>
  
  <pre><code>$config['language'] = "hungarian";
  
  /* default language abbreviation */
  $config['language_abbr'] = "hu";
  
  /* set available language abbreviations */
  $config['lang_uri_abbr'] = array("en" =&gt; "english");
  
  /* hide the language segment (use cookie) */
  $config['lang_ignore'] = TRUE;
  </code></pre>
