我是wordpress的初学者，最近我为我的在线商店安装了dokan插件，给了我问题，我读到解决方案是添加此代码
add_action('wp_enqueue_scripts', 'mgt_dequeue_stylesandscripts',99);
function mgt_dequeue_stylesandscripts() {
if ( class_exists( 'woocommerce' ) ) {
wp_dequeue_style( 'select2' );
wp_deregister_style( 'select2' );
wp_dequeue_script( 'select2');
wp_deregister_script('select2');
} }
我正在使用方便的商店模板，因此我将代码放在文件“function”中，当我使用此功能时，文本块停止工作，字面意思它们消失了，当我删除代码时它们又回来了，我怎么能解决它？
上述问题是我在上传横幅和照片时遇到了错误。
当我看到控制台时，我收到此错误
“Uncaught TypeError：$（...）。select2不是函数（...）”
在mi主题的函数帮助器中，函数是这个
