If you are having this problem after installation of the Perfect SEO Url plugin:

“Fatal error: Call to undefined function get_term_meta() in /home/liovena/public_html/wp-content/plugins/woocommerce-perfect-seo-url/includes/class-psu-rewrite.php on line 129″

Your WordPress version needs an update. If you will update to version 4.4 or higher, the error will be gone. You can update WordPress in your adminpanel or on your server.
