I tried the Loco plugin and added some custom translations but the strings weren’t changing on the front end.

I came up with this code but am not sure if it can work, if it does then the filter string I added might be wrong. But It also doesn’t work, maybe a simple tweak can make it work.

add_filter( ‘woodmart_frequently_bought_together_title’, ‘change_fbt_title’ );
function change_fbt_title( $title ) {
$title = ‘Complete the Collection’;
return $title;
}
