Canonical Tag in Magento - SEOMoz Tool Warning
-
This post is deleted! -
Which page is supposed to be the original? The canonical code seems fine to me.
-
Your url is:
http://www.mageclub.org/magento-extensions/contact-enhanced-magento-extension.html
You rel canonical is:
http://www.mageclub.org/contact-enhanced-magento-extension.html
Looks like a folder (/magento-extensions/) is missing.

Magento by default generates two URLs.
One direct product URL and one category alias product URL.
Thats why, we keep the canonical tag switched on, so that it can the search engines that, both the URLs page contents are the same. Just two URLs.
Not sure, why SEOMOZ tool is giving a warning.
-
SEOmoz, or any other tool on the web, won't be available to tell you if the canonical URLs are set up correctly or not. Instead they can give you a notification that the specific page has a canonical URL.
An advice in your case, do not use automatic canonical generation for ecommerce websites, because you might end up with two different urls with the same content having the canonical urls pointing to themselves.
Page A will tell Search Engines that Page A is the original version of the page, while Page B will tell Search Engines that Page B is the original version. If you would be the Search Engine, would you be confused?

I usually use the notifications that I get from SEOmoz to check and try to avoid situations as described above.
I hope it helped,
