Removing duplicate content caused by node/nid/talk pages Recently I installed the talk module, didn't like it and uninstalled it.  After removing it I have noticed that I have duplicate content listed under both the node ID and the node id followed by talk.  

For instance:  The page www.mysite.com/about-us is duplicated at the address www.mysite.com/node/4/talk as are all my pages.

In the talk.module file (which has been removed along with the entire talk module) I notice the line:   


  $items['node/%node/talk'] = array(


To me this looks like the line of code that created these talk pages, however being that I have removed the entire module, flushed caches etc. I do not understand how these pages still exist.  Any help would really be appreciated as I have been working on this now for several days with no answer.  Thanks in advance.
So /node/4 is your about page isn't it? you just added a url alias. Which means you can access the same page with /node/4 or with /about-us

To quote Clive from Non-existent URLs in Views 3 in drupal 7


  That's the expected behaviour - Drupal automatically routes you to the
  'parent' if it can't find the 'child' part of the URL


when I go to mywebsite.com/node/1/talk it displays the /node/1 content to me; even though, the url in the web browser says mywebsite.com/node/1/talk, and I haven't even installed the talk module at all.

Try going to mywebsite.com/node/4/ijustmadethisup and you'll see you get displayed /node/4

Therefore, this is just the default Drupal behaviour, nothing to do with the talk module.
