I have a view set up via a template and on that view are 4 pages that are shown as testimonials page.
In side the view the url is correct and good and it matches the content link.
All links I can find and test in durpal are functioning, from the testimonial page, from the Views UI and from the content list page.
One of those 4 pages has a trailing -0 added to it in the site map.
Obviously, this is giving a page not found error and error report in google webmaster tools.
I do not see another instance of this page that would cause drupal to create the duplicate page title with the trailing 0
I have cleared cache and rebuilt several times nothing worked. I ununstalled site map. ran cron - update script, cleared cache. Down loaded a fresh zip, installed and started fresh and same results.
I double checked the URL alias as well.
Not sure what is the cause. I first suspect views but I would expect the other 3 pages to have the same issue.
Next step would be to delete the page, rebuild map check to see if it persist. If clear create the page again.
