Won't write sitemap files when running from cron

[jknopp]

Isn't that the same as running it directly in the browser? I know that works fine. I suppose it is a solution to the issue, though more of a workaround than solving the actual problem. Unless you have a good idea of how to debug the problem though, it is probably the way to go.

In case if all permissions are definitely correct, it's hard to say what else might be wrong, and calling it in "web way" is probably a good option.
