 * Hey all,
 * Not sure if this is the right forum, but I was updating my child theme to not
   show the comments count alongside posts on my blog page and WordPress returned
   me an error. I’ve since returned the code to the exact way it was prior to the
   error but it’s still there.
 * I also just updated Jetpack and wondered if that might be causing an issue, deactivated
   then reactivated but no difference.

 * Warning: call_user_func_array() [function.call-user-func-array]: First argument
   is expected to be a valid callback, ‘-_header_background’ was given in /home/
   doucette/public_html/wp-includes/plugin.php on line 406
 * Anyone know how to fix this / what I’ve done wrong?
 * Thanks,
    Heather

 * Never mind folks – turned out to be something I hadn’t even touched! Commented
   out this line:
    `add_custom_image_header('-_header_background', 'ess_admin_header_background');`
 * Not entirely sure what it changed, since the site looks the same as it did previously,
   but the error is now gone.
