我正在构建一个购物车，现在我正在研究产品的类别系统。我必须从管理面板添加类别才能正常工作。
现在，当我想更新类别时，页面会继续加载，3-4分钟后，它会显示mozilla firefox中的service temporarily unavailable error和chrome中的404 error。
与托管服务提供商联系时，以下是他在邮件中发送的内容：
The issue that you are facing is mainly due to saturation of the number of fcgi processes allocated for your account. We allow 3 child process and for each child process, 256 worker processes. Once that limit is breached, you see that kind of error. However, those errors are auto-fixed once the number of processes reduce.

In order to fix the issue permanently, you need to optimize your codes or please go for VPS packages.
这里是类别文件夹的php代码index.php页面

好吧，当托管公司设置对服务器上的资源的硬限制时会发生这种情况。在这种情况下，您需要更改您的托管服务提供商。
无论如何，您的查询返回了多少行？
