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?
