Support » Plugin: Search by SKU for Woocommerce » WordPress 4.7 upgrade – WP_Hook

  • After upgrading to WP 4.7 i am getting the following notice in the admin page

    Notice: Indirect modification of overloaded element of WP_Hook has no effect in [relative path]/public_html/wp-content/plugins/search-by-sku-for-woocommerce/wp-filters-extra.php on line 64

    What does that mean? And how to fix it?

    P.S: Searching by SKU still works on the front-end.
