为什么我一直有致命的错误问题？

Keep having this fatal error on my website:

Fatal error: Call to undefined function trx_addons_vc_add_hide_param() in /homepages/5/d735247419/htdocs/clickandbuilds/YourJapan/wp-content/plugins/trx_addons/components/cpt/layouts/layouts_vc.php on line 99

tried to edit the function but didnt help

here is the code from line 99:

    $params = trx_addons_vc_add_hide_param(esc_html__('Custom Layouts', 'trx_addons'), true);
    foreach ($params as $param)
        vc_add_param("vc_row", $param);
