Thread: Help Needed with Excerpt Length Listings Page

Help Needed with Excerpt Length Listings Page

Love this child theme so switched to it today. My problem is that previously on child theme I had added the following to functions.php to increase the length of the excerpt on the listings page:-

function custom_excerpt_length( $length ) {
return 20;
}
add_filter( 'excerpt_length', 'custom_excerpt_length', 999 );

I am not able to do this with this child , can anyone help with guidance as to how to achieve this? It's very important to me that I can achieve it and I really don't want to roil back from this amazing child.

Cheers
