I've installed the Generator and set the permissions as directed. On the "Configuration" when I change the settings and click "Save", the page reloads with the default settings and none of my changes have been saved.
When I then go to the "Crawling" page and click "Run", the only thing that happens is that it redirects to the "Configuration" page with no error messages or information. "No sitemaps found" and the files that I created are empty. I have double- and triple-checked permissions.
It just simply...does nothing.
