    Hi, the plugin is working great but I am getting the following error, can you advise on the fix please? thanks

    [24-Jul-2021 09:29:47 UTC] PHP Warning: call_user_func() expects parameter 1 to be a valid callback, no array or string given in /var/www/vhosts/domainname.com/httpdocs/wp-content/plugins/woo-accordions/includes/accordion-tabs.php on line 30

    This is the code at line 30: <?php call_user_func( $tab[‘callback’], $key, $tab ); ?>
