How to remove Yoast SEO plugin comment from the source code

Since Wodrpess version 5 and later you can remove the annoying inline HTML-comment made by Yoast seo plugin with a single line. Removing the comment doesn’t affect any performance, but keeps your code a little bit cleaner.

Add the following line at the end of the functions.php file in your theme folder:

add_filter( 'wpseo_debug_markers', '__return_false' );

Enjoy!
