I am informed by Bing Webmaster Tools:

Large number of pages pointing to the same canonical URL for domain

http://mydomain.org/

Canonical tags can be used to help de-dupe URLs for pages with the same or very similar content. Bing has detected that your site is using what appears to be the same canonical URL for a large number of pages that are not the same. This may be indicative of a problem with your HTML template, content publishing system, or site code. You should review the source of your pages and check if the URLs used inside the <link rel="canonical" href="<url>" /> are not accidentally pointing to the same location for all (or too many) pages.

I search on the forum, and doesn't find other people has the same issue.

Can anyone please help?
Thank you.
