When I visit http//www.myforum.com/sitemap.php, it sends me to http//www.myforum.com/sitemaps.xml, and I get this message:

Page Not Found

The page you tried to access does not exist on this server. This page may not exist due to the following reasons:

1. You are the owner of this web site and you have not uploaded (or incorrectly uploaded) your web site. For information on uploading your web site using FTP client software or web design software, click here for FTP Upload Information.

2. The URL that you have entered in your browser is incorrect. Please re-enter the URL and try again.

3. The Link that you clicked on incorrectly points to this page. Please contact the owner of this web site to inform them of this situation.

What is going on?
I have set URL rewriting, and this is my .htaccess.bak:


RewriteEngine on

RewriteRule ^rss-?(l|s)?-?(m)?\.([xml|xml\.gz]+)$ rss.php?$1&$2 [L]
RewriteRule ^return/(.*)/(.*)/(.*)$ ad_ads.php?mode=paymentdo&status=$1&code=$2&id_ad=$3 [L]
RewriteRule ^return/(.*)/(.*)$ ad_ads.php?mode=paymentdo&status=$1&code=$2 [L]
RewriteRule ^return(.*)$ index.php [L]
