I keep getting the error bad flag delimiters. Here's my .htaccess file. I had used this on a different server and it worked dine but after I moved to a different one resulted the error. Any ideas?

RewriteEngine on
<Files .htaccess>
order allow,deny
deny from all
</Files>

<Limit GET POST>
order deny,allow
deny from all
allow from all
</Limit>

<Limit PUT DELETE>
order deny,allow
