Theme’s Content Width
Some functionality in Stackable uses your theme’s content width. To ensure the width is easily detected, make sure you define it in the theme’s functions.php file:
global $content_width;
$content_width = 640;<br>
Is this a necessary step with GP and/or what steps do you recommend?
no GP does not register that global variable.
i don’t know why they want the theme to add it….
if you need it then you can add it using this PHP snippet:
add_action( 'after_setup_theme', function(){
global $content_width;
$content_width = 640;
});
