about 500 internal server error !

[caogenyan]

hello, every one.

I installed get-simple on webhost, but because of questions for root .htaccess file, the website show 500 internal server error.
I found to deleted some codes, the website is OK.
The main reason is "Order" "Deny" "Allow" directives does not support by webhost.

deleted codes bellow:
<Files ~ "\.xml$">
Order allow,deny
Deny from all
Satisfy All
</Files>
<Files sitemap.xml>
Order allow,deny
Allow from all
Satisfy All
</Files>>

I want to know if this will affect the website's data security.
