.htaccess affecting url to sitemap

Morning all,

have had a problem were there were no rewrite rules in the .htaccess file which prevented the url to the sitemap working xyz.com/sitemap.xml.

Theis was new install of the latest version of WP, single install and the .htaccess was like this after the infinite was installed and activated

# Switch rewrite engine off in case this was installed under HostPay.

RewriteEngine Off

SetEnv DEFAULT_PHP_VERSION 53

DirectoryIndex index.cgi index.php

# BEGIN WordPress

# END WordPress

So I copied the .htaccess from another on my blogs that also runs infite and put that up instead:

# BEGIN WordPress

<IfModule mod_rewrite.c>

RewriteEngine On

RewriteBase /

RewriteRule ^index.php$ – [L]

RewriteCond %{REQUEST_FILENAME} !-f

RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule . /index.php [L]

</IfModule>

# END WordPress

No more sitemap.xml 404

But I guess my questions is “should infinite be writing the .htaccess file when its installed and activared”, oh by the way am using infinate verison 1.3.7

Cheers

Dave
