新搭建WordPress站点出现JQuery Widget系列错误求助

我搭建了一个纯净版WordPress站点（无插件、无第三方主题，仅官方原版程序），但未开始自定义就遇到一系列jQuery/JQuery UI相关Widget错误，导致插件页面无法正常显示、手动安装插件后无法删除等问题。

问题细节 #

• 插件页面无法正常显示，只能手动上传安装插件
• 删除手动安装的插件时触发最后一条aysDeleteUninstall相关错误

已尝试的无效方案 #

• ❌ 重新安装纯净版WordPress
• ❌ 克隆正常运行的站点至当前域名（原站点无此问题，克隆后错误依旧）
• ❌ 在functions.php中手动注册jQuery和jQuery UI脚本
• ❌ 联系服务器支持排查账户（未发现异常）
• ❌ 重启本地网络
• ❌ 清除服务器端、本地、浏览器所有缓存
• ❌ 安装控制jQuery/jQuery UI版本的插件
• ❌ 安装jQuery UI Widgets插件
• ❌ 在后台手动添加jQuery/jQuery UI脚本
• ✅ 清除Cloudflare缓存（无效果）

解决建议 #

1. 检查jQuery UI Widget核心文件是否缺失/损坏 #

WordPress官方包中wp-includes/js/jquery/ui/目录下应包含widget.min.js文件，这是所有UI组件依赖的核心：

• 通过FTP或文件管理器查看该文件是否存在，若缺失，从官方WordPress安装包中提取对应版本的文件上传
• 若文件存在，对比文件哈希值与官方包一致，排除文件损坏问题

2. 排查load-scripts.php的脚本加载顺序 #

错误中显示load-scripts.php加载了jquery-core但未正确加载jquery-ui-widget，可能是脚本加载逻辑被干扰：

• 临时禁用Cloudflare的Auto Minify功能，避免JS文件被错误合并
• 检查服务器端是否有自定义的functions.php或mu-plugin修改了脚本加载优先级
• 尝试在wp-config.php中添加define('SCRIPT_DEBUG', true);开启调试模式，查看未压缩的脚本错误，定位具体加载问题

3. 服务器环境与PHP配置检查 #

• 检查PHP版本是否符合WordPress 6.3.1的要求（推荐PHP 7.4+）
• 查看服务器的open_basedir配置，确保WordPress能正常读取wp-includes目录下的JS文件
• 检查服务器的文件权限，wp-includes/js/目录及子文件权限应设置为755，文件权限为644

4. 手动修复脚本依赖关系 #

在主题的functions.php中添加以下代码，强制确保jquery-ui-widget在所有UI组件前加载：

function fix_jquery_ui_dependencies() {
    wp_deregister_script('jquery-ui-widget');
    wp_register_script('jquery-ui-widget', includes_url('js/jquery/ui/widget.min.js'), array('jquery'), '1.13.2', true);
    
    // 重新注册所有依赖widget的UI组件
    $ui_components = array('mouse', 'draggable', 'slider', 'accordion', 'resizable', 'controlgroup', 'checkboxradio', 'button', 'dialog', 'menu', 'autocomplete', 'sortable', 'droppable', 'tabs');
    foreach ($ui_components as $component) {
        wp_deregister_script('jquery-ui-' . $component);
        wp_register_script('jquery-ui-' . $component, includes_url("js/jquery/ui/{$component}.min.js"), array('jquery-ui-widget'), '1.13.2', true);
    }
}
add_action('wp_enqueue_scripts', 'fix_jquery_ui_dependencies', 999);
add_action('admin_enqueue_scripts', 'fix_jquery_ui_dependencies', 999);

5. 排查CDN或服务器缓存的深层问题 #

• 若使用Cloudflare，开启Development Mode后再次测试，避免缓存的旧JS文件干扰
• 检查服务器端的OPcache或其他PHP缓存，清空后重启PHP服务
• 尝试切换服务器的PHP运行模式（如从CGI切换到FPM），排除运行模式导致的文件读取异常
