As soon as I activate the plugin I loose the next page function on posts. I use the
<!--nextpage--> on longer post and this stops working after installing WordPress SEO. I did deactivate the plugin and it started to work again and then 2 days later when I activated it again it stopped working. You can see on following adress: try go to Page 2 or 3 it does not work and it redirects you back to Page 1. I have no clue why it behaves like this!
