Question

我已经为WordPress下载了一个较旧的插件，但是每当我尝试激活它时，都会引发此错误：

致命错误：无法在[filelocation]第41行的写上下文中使用函数返回值

function poa_ps_enqueue_scripts() {


    if ( is_category() ) :
        $cat = get_category(get_query_var('cat'));
        $slides_loop = new WP_Query( array( 'post_type' => POA_POST_TYPE_NAME, 'category__in' => $cat->term_id, 'posts_per_page' => -1, 'order' => 'asc' ) );
        if ( !empty($slides_loop) ) :

            // reveal.js scripts

            );
            wp_localize_script( 'reveal_front_js', 'php_vars', $php_vars );

            wp_enqueue_script( 'reveal_front_js' );

            if (!empty(get_option('poa_option_name')['poa_position_navigation'])) {
                $position = esc_html(get_option('poa_option_name')['poa_position_navigation']);
                if ($position == 'left' || $position == 'right') {
                    wp_enqueue_style( 'position_css', POA_PLUGIN_URL . '/css/poa-position-nav.css', array(), '2017' );
                }
            }
            endif;
    endif; //is_category()
}

有人知道我该如何解决？ wordpress网站还告诉我我正在运行旧版本的PHP，这是否也可以连接错误？如果可以的话，可以不更新PHP而将其修复吗？
