简要说明：任何以数字开头的搜索友好网址都会转到不应该存在的已损坏页面，而不是自定义404错误页面
详细信息：任何部分现有网址＆amp;随机字符似乎返回一个损坏的页面，而不是404页面。
示例正确进入404错误页面的非退出网址： http://www.shareandcare.org/asdasd或http://www.shareandcare.org/a22sdasd
示例不存在或部分存在的网址，应该转到404错误页面： http://www.shareandcare.org/17-progsdsadsad和http://www.shareandcare.org/27-progrsdsads
因为他们以数字开头，所以他们加载了我认为不存在的破页。好像他们正在寻找一个joomla id，但即便如此，为什么它会被打破呢？

如果将以下代码复制/粘贴到.htaccess文件中，则对不存在的文件或文件夹的所有请求都将返回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：
