Joomla K2 Troubleshooter. Error “The Name or Email Address you typed is already in use!”

Testing K2 Joomla Joomla is an award-winning content management system (CMS), which enables you to build Web sites and powerful online applications. Many aspects, including its ease-of-use and extensibility, have made Joomla the most popular Web site software available. Best of all, Joomla is an open source solution that is freely available to everyone. components we’ve located the following issue: trying to post a comment using the name and the email if the registered user (typing them into the name and email fields) you can see the error message:

The Name or Email Address you typed is already in use!

To resolve this issue you need to perform some updates to the K2 core file.

Open your Joomla installation directory and open “components/com_k2/models/item.php” with your editor.

There locate and delete or comment the following code:

if  ($user->guest){
  $db = & JFactory::getDBO();
  $query = "SELECT COUNT(*) FROM #__users WHERE  name=".$db->Quote($userName)." OR  email=".$db->Quote($commentEmail);
  $db->setQuery($query);
  $result = $db->loadresult();
  if ($result>0){
  echo JText::_('The name or email address you typed is already in use!');
  $mainframe->close();
  }
}

In other words replace it with

  /*if  ($user->guest){
  $db = & JFactory::getDBO();
  $query = "SELECT COUNT(*) FROM #__users WHERE  name=".$db->Quote($userName)." OR  email=".$db->Quote($commentEmail);
  $db->setQuery($query);
  $result = $db->loadresult();
  if ($result>0){
  echo JText::_('The name or email address you typed is already in use!');
  $mainframe->close();
  }
  }*/

This should solve the issue.
