I don't know what the F**K he is doing with the plugin. It is a mess up now a days. With every update there's more bug than bug fixes. Over a Dozen of my site still have that "This is a Yoast Test Title" as title on every page of the site because of a bug in the plugin which killed the ranks of all those sites. And now I can't even save any sh*t because there's no save button. I hate you Yoast!!!
Sorry about the language!!!
