I want to make a dynamic sitemap for Google Webmaster tools. But for some reason, I can't make it work. I write some lines in the htaccess for these purposes (RewriteRule), and it work fine. In fact, validation is OK: validation
But Google print this error every time (here is the english translation):
We were unable to read your Sitemap. It may contain an entry that can not recognize. Validate the sitemap before re-upload
Weirdly, when I open sitemap.php in the browser and I save the file as xml, Google doesn't print any error.
What's the problem?
EDITED. Here is the URL:Dynamic Sitemap
