我最近完成了自己的代码混合和匹配插件，以处理WooCommerce网站上的表格（使其更适合于购买sutff的公司）。它可以在本地正常运行，但是当我将其放在现场的网站上时，使用链接/按钮将您定向到其他页面（网站上）时，我会白屏死机-我不知道为什么！有什么想法吗？
我真的没有尝试过任何东西，因为我对woocommerce，wordpress和PHP的了解最多...初学者。

需要更多代码，我将对其进行编辑并将其提供给您，我还对my-address.php（woocommerce文件）做了一些更改。
我想要的结果：不会出现死亡白屏。
编辑：我试图为PHP添加更多内存，但没有用。
答案 0 :(得分：2)
在您的wp_config.php中（在网站的根目录中），您可能有以下一行：
define('WP_DEBUG', false);
将此更改为：
define('WP_DEBUG', true);
并再次检查您的死亡白屏-它应该向您显示哪个文件以及该文件中的哪一行，发生了错误：-）

感谢rblarsens回答，我发现了错误：

这仅仅是由第一个空格之前的空格（“”）引起的
