我是 wordpress 的初学者，最近我为我的网上商店安装了 dokan 插件，给了我一些问题，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，所以我将代码放在文件“函数”中，当我使用这个函数时，文本块停止工作，实际上它们消失了，当我删除代码时它们又回来了，怎么可能我解决？
上面的问题是我在上传横幅和照片时出错。
函数的代码是这样的
