Canonical issues means your website have multiple URLs like <!-- w --><a class="postlink" href="http://www.abc.com">www.abc.com</a><!-- w -->, abc.com, <!-- w --><a class="postlink" href="http://www.abc.com/index">www.abc.com/index</a><!-- w -->, etc..You can solve this problem by putting a 301 redirection code on website.
