Removing “generator” WordPress Meta Tag

I tried this once before but it didn’t work — WordPress will ultimately try to add a generator meta tag. Since I use the infamous Hybrid Core, my situation was a little different.

In hybrid-core/hybrid.php, there’s an action hooked up to after_setup_theme that runs default_filters. Here’s a snippet:

/* Move the WordPress generator to a better priority. */
remove_action( 'wp_head', 'wp_generator' );
add_action( 'wp_head', 'wp_generator', 1 );

/* Add the theme info to the header (lets theme developers give better support). */
add_action( 'wp_head', 'hybrid_meta_template', 1 );

You’ll notice the removal of a wp_generator and then a new action hook with priority. No wonder my previous attempts didn’t work — they were running at default priority. To counter Hybrid’s addition, I simply applied a matching priority to my removal too, among other things:

function convergence_remove_header_meta() {
  remove_action('wp_head', 'wlwmanifest_link');
  remove_action('wp_head', 'rsd_link');
  remove_action('wp_head', 'wp_generator', 1);
  remove_action('wp_head', 'hybrid_meta_template', 1);
}
