Facebook share working only on certain pages
It appears that the facebook button only works on pages that are in the root folder. If the pages are nested away in subfolders all bets are off.
To see what I mean please go to www.milicainthehat.com, here it works.
Then click on the About and it works there too.
But if you go to any of the Shop subcategories or any other subcategory it does not.
