Yes Peter, I have outdated WP and I can not update. Then, if Yoast doesn't support version of WP like 3.8, 3.7, 3.6 etc... I can not update plugin Seo Yoast... And the only plugin I have found about export Seo Yoast to All in one Seo plugin dosen't work very well (SEO Data Transporter)... I am lost... (And I think I am not the only one..)
