Background of the issue:
I am trying to resolve a PHP warning that appears many times a day and seems to be slowing down queries. The error is: PHP Warning: Undefined array key "values" in /data/wordpress/htdocs/wp-content/plugins/woocommerce-multilingual/inc/class-wcml-tp-support.php on line 142.
Symptoms:
PHP Warning: Undefined array key "values" in /data/wordpress/htdocs/wp-content/plugins/woocommerce-multilingual/inc/class-wcml-tp-support.php on line 142. This error appears frequently and seems to slow down queries.
