如何将不存在的 Joomla URLS 重定向到我们的 404 错误页面？

Question

简介：任何以数字开头的搜索友好 URL 都会转到不应存在的损坏页面，而不是自定义 404 错误页面

详细信息：任何部分现有的 url 和随机字符似乎返回一个损坏的页面，而不是 404 页面。

示例 正确转到 404 错误页面的非退出网址： http://www.shareandcare.org/asdasd 或 http://www.shareandcare.org/a22sdasd

示例应该转到 404 错误页面的不存在或部分存在的 url： http://www.shareandcare.org/17-progsdsadsad 和 http://www.shareandcare.org/27-progrsdsads

因为它们以数字开头，所以它们加载了我认为不存在的损坏页面。就好像他们正在寻找一个 joomla id，但即便如此，为什么它会出现损坏？

我的 htaccess 如下，任何解决方案将不胜感激：

如果您将以下代码复制/粘贴到 .htaccess 文件中，所有对不存在的文件或文件夹的请求都将返回您的 index.php 文件的内容。

<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule ^(.*)$ / [L,QSA]
</IfModule>

每一行的含义如下：

• RewriteEngine on：启用运行时重写引擎。
• RewriteCond %{REQUEST_FILENAME} !-f：重写将发生 请求的文件名不是常规文件，或者文件不是 存在。
• RewriteCond %{REQUEST_FILENAME} !-d：重写将发生 请求的文件名不是目录，或者如果目录不是 存在。
• RewriteRule ^(.*)$ / [L,QSA]：如果以上条件都匹配（ 请求的文件不是文件，不是目录，也不存在） 然后 URL 将被重写到您网站的根目录。
• “L”表示重写过程应立即停止 应用此规则后，“QSA”表示任何查询 来自原始请求 URL 的字符串必须附加到重写 目标。
