Product attribute slug is too long (28 characters max).

Google did not fix my problem so..

Anyone here know how to increase the character limit for woocommerce product attribute slug, now it has a limit of 28 characters i need max 40.

I’m testing a local site where product information comes from imported xml files, sometimes certain attribute names are just longer than 28 characters..

Tried to change the values in wc-attribute-functions.php, and changed 28 to 40, but that didnt help..

// Validate slug.
if ( strlen( $slug ) >= 40 ) {
/* translators: %s: attribute slug */
return new WP_Error( ‘invalid_product_attribute_slug_too_long’, sprintf( __( ‘Slug “%s” is too long (40 characters max). Shorten it, please.’, ‘woocommerce’ ), $slug ), array( ‘status’ => 400 ) );
