I had upgraded to WP 3.4.2. Immediately, I get the following error messages:
Notice: add_custom_image_header is deprecated since version 3.4! Use add_theme_support( 'custom-header', $args ) instead.
Notice: add_custom_background is deprecated since version 3.4! Use add_theme_support( 'custom-background', $args ) instead.
I looked at the demo installation of WP-Creativix hosted by WordPress. It works without issue. What am I doing wrong? I am not a programmer.
