I figure out a xml sitemap for my website. In .htaccess, if I comment (RewriteRule ^(.*)/?$ index.php?rp=$1 [L]) line then all xml sitemap works fine, but my website pages doesn't work. Please check this links.... www.streaminghub.org/test/sitemap.php -- Working www.streaminghub.org/test/sitemap_1.xml --- working www.streaminghub.org/test/video/5439/samsung-nf110-english-hands-on-at-ifa-2010/ --- Not working My .htaccess file.... <IfModule mod_rewrite.c> RewriteEngine on RewriteBase /test/ RewriteRule ^embed/([^/]*)/$ /embed.php?id=$1 [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d **RewriteRule ^(.*)/?$ index.php?rp=$1 [L]** **RewriteRule ^sitemaps.xml sitemap.php** **RewriteRule ^sitemap_(.*).xml?$ sitemap.php?page=$1 [L]** </IfModule> I think it's a .htaccess issue, I am using phpvibe script. I don't have knowledge with .htaccess, kindly help me to figure this issue. Thank you.
