Php 重写cond%{REQUEST_FILENAME}-f并重写cond%{REQUEST_FILENAME}-d工作不正常

我的.htaccess文件包含以下代码

Options +FollowSymlinks
RewriteEngine On

#php_flag display_errors on

# compress text, html, javascript, css, xml:
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/json
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript


# Or, compress certain file types by extension:
#<files *.html>
#SetOutputFilter DEFLATE
#</files>



#RewriteCond %{REMOTE_HOST} !^12\.188\.175\.226
#RewriteCond %{REQUEST_URI} !/maintenance\.html$
#RewriteRule (.*).html$ /maintenance\.html [R=302,L]

#RewriteCond %{REMOTE_HOST} !^12\.188\.175\.226
#RewriteCond %{REQUEST_URI} !/maintenance\.html$
#RewriteRule ^$ /maintenance\.html [R=302,L]

RewriteCond %{HTTP_HOST} ^(.*)find-junkyards.com [or]
RewriteCond %{HTTP_HOST} ^(.*)findjunkyards.net [or]
RewriteCond %{HTTP_HOST} ^junkyardsnearme.com
RewriteRule (.*) http://www.junkyardsnearme.com/$1 [R=301,L]

#RewriteRule (.*) http://www.junkyardsnearme.com/$1 [R=301,L]

#RewriteRule (.*) http://www.junkyardsnearme.com/$1 [R=301,L]

RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-f
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-d
#RewriteRule ^(.*)$ index.php?_req=/$1&%{QUERY_STRING} [L]
RewriteRule ^(.*)$ index.php/$1 [L]


#ErrorDocument 404 http://dev.junkyardsnearme.com/admin/accounts/error404 

它将不允许我通过网站流量。我也试过了

RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-f
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-d
#RewriteRule ^(.*)$ index.php?_req=/$1&%{QUERY_STRING} [L]
RewriteRule ^(.*)$ index.php/$1 [L]

但对我来说还是不行

任何想法为什么这不工作，请尽快回答这将是巨大的帮助

提前感谢。

此.htaccess位于何处，提供了什么URL 404？验证.htaccess是否已启用，通过将相同的垃圾随机文本放在.htaccess上，看看它是否会生成500个内部服务器错误？感谢您的建议，但我得到了解决方案。htaccess代码将我重定向到一个controller.php文件，在该文件中写入错误消息，然后我更改了路径，并显示了我自己的自定义404页面。那么您的问题现在解决了吗？

RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-f
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_FILENAME} !-d
#RewriteRule ^(.*)$ index.php?_req=/$1&%{QUERY_STRING} [L]
RewriteRule ^(.*)$ index.php/$1 [L]
