I got the same message in all of my installations (if WP_DEBUG is set on true). But it disappears after commenting out the following part in admin/admin.php (or only the if-clause):
if (mh_magazine_lite_official_theme()) {
add_action(‘admin_notices’, ‘mh_magazine_lite_admin_notice’);
add_action(‘wp_loaded’, ‘mh_magazine_lite_hide_notice’);
add_action(‘admin_menu’, ‘mh_magazine_lite_theme_info_page’);
}
Maybe this helps in fixing the problem.
Best regards
Axel
