Base thread is this one: https://wordpress.org/support/topic/shop-page-issue-with-all-in-one-seo-plugin?replies=12
Problematic page is here: http://namaki.fr/maquillage-enfant-bio/
I have the very last SEO all-in-one plugin (2.1.4) and this problem still exists.
MalteseFalcon uses a beautiful solution described in the thread but it's not working for me. I've tried to upload an alternative header.php file with different names header-shop.php, header-maquillage-enfant-bio.php, header-boutique.php (french translation for "shop") to no avail ... Any help would be greatly appreciated.

You can set the "Shop" page title tag by putting the text you want in "Archive Title Format:" on All In One SEO settings page.
However there is no longer Archive Title Format in 2.1.4 All-In-One SEO plugin settings page.
So I am stuck I cannot edit title or meta tag for this page which greatly impacts my SEO. Any help?
