Comment on WordPress SEO Tutorial by SEO Dave.

WordPress SEO The Platinum SEO Pack Plugin would have been responsible for the nofollow links, as you’ve disabled it they have been removed.

The messed up URLs for posts etc… that have a URL ending %PostName% will be related to the Permalinks settings and/or the .htaccess file.

Under

Settings >> Permalinks

The Custom Structure box should contain something like:

/%postname%

Looks like you are using

/%PostName%

The uppercase P and N is the problem, it’s not recognised by WordPress as postname. Change it to

/%postname%

And the problem should be fixed.
