RECOMMENDED: No reference to the_post_thumbnail() was found in the theme. It is recommended that the theme implement this functionality instead of using custom fields for thumbnails.
RECOMMENDED: No reference to add_theme_support( ‘custom-header’, $args ) was found in the theme. It is recommended that the theme implement this functionality if using an image for the header.
RECOMMENDED: No reference to add_theme_support( ‘custom-background’, $args ) was found in the theme. If the theme uses background images or solid colors for the background, then it is recommended that the theme implement this functionality.
RECOMMENDED: Screenshot size should be 600×450, to account for HiDPI displays. Any 4:3 image size is acceptable, but 600×450 is preferred.
RECOMMENDED: Screenshot dimensions are wrong! Ratio of width to height should be 4:3.
RECOMMENDED: add_custom_background found in the file functions.php. Deprecated since version 3.4. Use add_theme_support( ‘custom-background’, $args ) instead.

INFO: header.php The theme appears to use include or require. If these are being used to include separate sections of a template from independent files, then get_template_part() should be used instead.
