Thank you for your answer! No, on moodle.org, it is OK as well. I am running my site on a VPS, which is operated by a company not reletaed to my school, so I need to have some information before I call them with my problem. The VPS runs under Linux, so IIS shouldn't be the problem. I am using the latest decaf theme, but previously I'd used something else.
