Duplicated content on homepage I've found that my site is showing duplicated content, I think it was when I installed Pathauto. The nodes are not duplicated though but seems to be multiple aliases.

I've since tried using Global Redirect but it hasn't solved the issue. And even worse, some items are showing up three times now!

For example

http://biosphericproject.php5.demo.faelix.net/content/what-we-mean-forest-gardening-1
http://biosphericproject.php5.demo.faelix.net/content/what-we-mean-forest-gardening
http://biosphericproject.php5.demo.faelix.net/content/what-we-mean-forest-gardening-0

Confused,

You have to delete those duplicate alias by going to the alias list at admin/config/search/path (in Drupal 7). It's not an automatic task, I'm afraid.
Or you can delete all alias and bulk recreate them using the Bulk Update function. That would be an automatic process.

As a last step, you should check Alias Settings at admin/config/search/path/settings. I think you should change the "Update action" to "Create a new alias. Delete the old alias.".
