Hi,

I followed the instructions on http://doc.silverstripe.org/sapphire/en/reference/staticpublisher
but i get Error msg:

[User Error] Uncaught Exception: Object->__call(): the method 'subpagestocache' does not exist on 'Page'

 function allPagesToCache() {
            // Get each page type to define its sub-urls
        $urls = array();

        // memory intensive depending on number of pages
        $pages = Subsite::get_from_all_subsites("SiteTree");

        foreach($pages as $page) {
        $urls = array_merge($urls, (array)$page->subPagesToCache()); //Exception thrown
        }

        return $urls;
    }
