WooCommerce Product Vendors: Change vendor URL slug

function.php

add_filter( 'product_vendors_vendor_slug', 'change_vendor_url_slug' );
function change_vendor_url_slug( $slug ) {
  $slug = 'new_url';
  return $slug;
}

the code above is outdated since woothemes changed the filter name to wcpv_vendor_slug
add_filter( 'wcpv_vendor_slug', 'change_vendor_url_slug' );
function change_vendor_url_slug( $slug ) {
$slug = 'new_url';
return $slug;
}

update the permalinks, for the change to reflect the new slug

Still works like a charm, thank you!

Doesn't seem to work anymore

(WooCommerce Product Vendors 2.1.17)

This wouldn't have worked since v2.0 of Product Vendors when the codebase was largely refactored.

@hlashbrooke - Dang!

Oddly enough, this is the same change suggested in the official WooCommerce documentation.
A workaround I've used is to change the language to en_CA, then modify the .po file to reflect the necessary changes, leaving the rest of lines untouched. You then select English (Canada) as the language for the WooCommerce site and it will show the changes.
