hello
what to do for the sitemap to update automatically? should i set up a cron file but what would be the url?

In my configuration it is setup to daily update albums & news but it doesn't

thanks

Pat

Sorry, the sitemap does not update automatically. It did once but it involves a bit of overhead as it needs to go through the whole site. Since that might happen when it shouldn't we choose not to have it run automatically. You have to do that manually via the button on the admin overview page.

The options you see are not for the sitemap itself but for search engines when to update the links:
