运营最久的进出口企业：解决WooCommerce结账页面加载问题
问题描述：用户的WordPress+WooCommerce商城网站突然出现结账页面无法加载的问题。
Problem Description: A WordPress+WooCommerce e-commerce site suddenly experienced checkout page loading issues.
主要症状：WooCommerce结账页面一直卡在加载状态，无法完成订单支付流程。通常在结账页面的"review order"部分会通过AJAX加载付款方式和总计金额，如果出现问题就会导致页面卡住。
Main Symptoms: The WooCommerce checkout page gets stuck loading, preventing order completion. Normally the "review order" section loads payment methods and totals via AJAX - any issues here cause the page to freeze.
排查步骤 Troubleshooting Steps:
1. 检查WooCommerce系统状态
访问WooCommerce > 系统状态，查看是否有错误提示。
1. Check WooCommerce System Status
Go to WooCommerce > System Status to check for error messages.
2. 检查WordPress设置
确保设置 > 常规中的URL地址匹配正确，因为AJAX请求不能跨不同地域工作。
2. Check WordPress Settings
Ensure URLs in Settings > General match correctly, as AJAX requests can't work across different domains.
3. 排查JavaScript错误和冲突
尝试切换系统主题，查看问题是否解决。
逐个禁用插件，排查可能的插件冲突。
3. Check for JavaScript Errors/Conflicts
Try switching to a default theme to see if the issue resolves.
Disable plugins one by one to identify potential conflicts.
4. 检查AJAX响应
在浏览器开发者工具中查看网络请求，特别是?wc-ajax=update_order_review的响应。
正常应为JSON格式，如果返回HTML则可能是根目录存在index.html文件导致的。
4. Check AJAX Responses
In browser developer tools, check network requests, especially the ?wc-ajax=update_order_review response.
Normal response should be JSON; HTML responses may indicate an index.html file in the root directory.
5. 检查CDN设置
最终发现客户使用了Cloudflare CDN，禁用CDN后问题解决。
需要检查并调整CDN的加速规则。
5. Check CDN Settings
Finally discovered the client was using Cloudflare CDN - disabling it resolved the issue.
Need to check and adjust CDN acceleration rules.
解决方案：经过上述排查和调整后，网站结账功能恢复正常。
Solution: After the above troubleshooting and adjustments, the checkout functionality returned to normal.
