Why on "Titles & Metas" I don't see any field. I think that since I installed a new version of the Yoast WordPress SEO with a new type of menu the fields disappeared. I just see the tabs (General, Home, Post Types, Taxonomies, Other, Help) and then just below the "Save Settings" button. Nevertheless, the software still keeps the old meta, but without giving em a chance to change it.
I have installed WPML multilingual plug-in.
