I have activated the Canonical URL option, which should be good.
However, while creating our website's sitemap, it came out with 3 Broken Links (Error 404 - not found).
Checking the code of one of the files shown as having broken links, I found the following code (inserted automatically by All In One SEO):
<!-- All in One SEO Pack 184.108.40.206 by Michael Torbert of Semper Fi Web Design[389,396] -->
<link rel="canonical" href="http://www.astrasuite.com/astrablog/page/2/" />
<!-- /all in one seo pack -->
Well, this URL is incorrect -> http://www.astrasuite.com/astrablog/page/2/
and it definitely is a broken link.
It should be -> http://www.astrasuite.com/astrablog/?paged=2
I deselected the Canonical URL option, and all went well with the Sitemap generation.
Michael Torbert, or anyone, any ideas ?
