In my Drupal based website, all links that I added from CKeditor open as (target="_blank"
Link example: (<a href="node/add/name">Name</a>)
After adding, example from html source: (<a target="_blank" rel="nofollow" href="node/add/name">Name</a>)
As you see, the 'target="_blank" rel="nofollow"' added automatically.
How can I solve this problem?
