...Actually if i go to end product page, it gets meta tag description from lang_en.php which is mentioned in admin panel General Configuration. instead of showing from following code
is unable to show meta tag description in end product page.
However above code works in other all main menu and category pages and show the meta tag description successfully in source code. ...But it not works in end product page.
So my question is how i can also show meta tag description in end product page through this code ==>
