网站链接混乱// .htaccess

I screwed up my .htaccess` file and now my links are messed up.

for example www.cardler.com/contact.php changes to www.cardler.com/awstats/contact.php

if you manually type in cardler.com/contact.php it works...

Link: www.cardler.com/index.php - try it out by clicking on the contact button.

.htaccess

    RewriteEngine on
    DirectoryIndex index.php

    RewriteCond %{REQUEST_FILENAME}.php -f
    RewriteCond %{REQUEST_URI} !/$
    RewriteRule (.*) $1\.php [L]
