解决步骤 #

1. 临时恢复页面编辑能力 #

• 登录WordPress后台，进入插件 > 已安装插件
• 找到Dokan Lite插件，点击停用
• 此时再尝试用Elementor编辑页面，应该能正常打开，先恢复或重新编辑页面内容

2. 修复Dokan Lite代码问题 #

错误原因是own_product_not_purchasable_notice方法中，获取当前产品的函数返回了false，却直接调用get_id()方法。添加判断即可避免报错：

• 通过FTP或主机文件管理器，找到文件/wp-content/plugins/dokan-lite/includes/Product/Hooks.php
• 打开文件定位到第406行，在调用get_id()前添加产品存在判断：

  // 原代码示例：
  $product_id = $product->get_id();
  
  // 修改为：
  if ( ! $product ) {
      return;
  }
  $product_id = $product->get_id();
  

• 保存文件后重新启用Dokan Lite插件

3. 更新Dokan Lite到最新版本 #

该错误大概率是插件兼容性bug，官方可能已修复：

• 后台进入插件 > 已安装插件，检查Dokan Lite的更新提示
• 点击更新插件，完成后测试页面是否恢复正常

4. 检查插件与主题兼容性 #

• 确认WooCommerce、Elementor Pro、Dokan Lite、Astra主题均为最新版本
• 若更新后仍报错，切换到WordPress默认主题（如Twenty Twenty-Four）测试，排查主题兼容性问题

5. 重新设置WooCommerce页面 #

若页面仍空白：

• 进入WooCommerce > 设置 > 高级，点击页面设置下的恢复默认页面
• 重新用Elementor编辑这些页面，设置自定义内容
