Php .htaccess破坏了我的ajax

我尝试用.htaccess删除url的index.php部分，现在ajax内容将不再加载，即使我删除了.htaccess。以下是.htaccess的外观：

<IfModule mod_rewrite.c>
        RewriteEngine On
        RewriteBase /

        # Removes index.php from ExpressionEngine URLs
        RewriteCond %{THE_REQUEST} ^GET.*index\.php [NC]
        RewriteCond %{REQUEST_URI} !/system/.* [NC]
        RewriteRule (.*?)index\.php/*(.*) /$1$2 [R=301,NE,L]

        # Directs all EE web requests through the site index file
        RewriteCond %{REQUEST_FILENAME} !-f
        RewriteCond %{REQUEST_FILENAME} !-d
        RewriteRule ^(.*)$ /index.php/$1 [L]
</IfModule>

---

最终，它成功地使用了这个.htaccess

<IfModule mod_rewrite.c>

RewriteEngine on
RewriteBase /

RewriteRule ^content/(.*)\.(txt|md|mdown)$ error [R=301,L]
RewriteRule ^site/(.*) error [R=301,L]
RewriteRule ^kirby/(.*) error [R=301,L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*) index.php [L]

</IfModule>

重新启动发动机
重写基/
重写规则^content/（.*）\（txt|md|mdown）$error[R=301，L]
重写规则^site/（*）错误[R=301，L]
重写规则^kirby/（*）错误[R=301，L]
重写cond%{REQUEST_FILENAME}-F
重写cond%{REQUEST_FILENAME}-D
重写规则^（.*）index.php[L]

ajax以前工作过吗？是的。甚至连一个都没有。htaccess…

<IfModule mod_rewrite.c>

RewriteEngine on
RewriteBase /

RewriteRule ^content/(.*)\.(txt|md|mdown)$ error [R=301,L]
RewriteRule ^site/(.*) error [R=301,L]
RewriteRule ^kirby/(.*) error [R=301,L]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*) index.php [L]

</IfModule>
