How to enable Post Formats
WordPress 3.1 includes a new feature called Post Formats that lets the site admin enable additional post formats besides the default one termed as "Standard" when creating/editing a post.
To use this feature, add the following to your theme's functions.php:
// ADD POST FORMATS add_theme_support( 'post-formats', array( 'aside', 'chat', 'gallery', 'image', 'link', 'quote', 'status', 'video', 'audio' ) );
If you have not used functions.php in BuilderChild-Default so far, download this file, name it as functions.php and upload it to your child theme directory, i.e., to wp-content/themes/BuilderChild-Default.
