I have installed Header Tag SEO, it seems to work fine, but I can't change the title of some page "Replace me in Page Control under index.php".
In admin panel > Header Tag SEO > Page control, the dropdown menu "Select an option" is almost empty, there are only 3 items ("Select a file", "Show All Files" and "Add Missing Pages"), so I can't change title and description of index.php for example.
How can I fix this ?
In the database ("headertags" table), there is a row for each following page : index.php, product_info.php, product_reviews.php, product_reviews_info.php, product_reviews_write.php and specials.php, with language_id = 4 (the language_id of the store)
When I try the test page, I got at the bottom of the page :
languages in the Header Tags table are: 2 ( Deutsch ).
languages in the Header Tags table are: 3 ( Español ).
languages in the Header Tags table are: 1 ( English ).
There is no language 4 (French), I don't what it means...
