Hi,
my website (www.casbahclub.it) has a few pages that are always the same, I means they include a shortcode which call functions PHP from an external plugin and update the page content (for example the page content is just [shortcode]).
In this case, the page doesn't result "upgrade" for Google XML plugin because last modified date is always the same in wordpress!
How can I automatically update the modified date in wordpress?
Do you have a solution for these pages?
Thank you very much
