Genesis, being the most popular commercial WordPress theme in the market, provides many customization options for the web masters. But, still I feel it could have been better if it had direct support for customizing few basic options like Post Info and Post Meta. After installing the Genesis child theme, most of us may have a requirement to either customize or to completely remove Post Meta and Post Info sections.
Post Info contains Date, Author and the Comment information by default. Post Meta contains Tag and Category information for all the posts on the home page and also on the individual pages. If you have installed the latest Genesis 2.x HTML 5 theme, then unfortunately the steps mentioned in the official StudioPress guide will not be helpful to remove the Post Meta and Post Info information.
Instead, you can make use of the below code snippet for removing the Post Info,
remove_action( 'genesis_entry_header', 'genesis_post_info', 12 );
and the below code snippet to remove Post Meta,
remove_action( 'genesis_entry_footer', 'genesis_post_meta' );
Remember, you need to add these two lines of code at the end of functions.php which is part of your child theme.
