I have a company redesigning my site, and now the sitemap generator isn't working right. Since I didn't install it, I'm not sure what to do. Getting the following errors when I click "save" on the main generator page.
Config file is not writable: ..../generator/config.inc.php
Datastorage folder is not writable: ....generator/data/
Sitemap file is not writable: ....generator/data/sitemap.html
