I have a site which is in production.
WordPress 3.7.1 + W3 Total Cache (I know it's not conected with browser cache)
I updated some files (css, some php and js)
with W3 Total Cache, I combine and minify css (which automatically generates name) So I cleaned minify cache + changed javascript version
wp_register_script( 'scrips', get_stylesheet_directory_uri() . '/js/scripts.min.js', array('jquery'), '1.3', true );
I asked some users and they gave me their screenshots and they have a problem with browser cache (probbly css). As soon as they clean their cache, problems are gone.
What should I do? Users are coming back )
