Can't log in, wiki complains that cookies are disabled

Hello, I'm getting the following error when trying to login to the wiki: "Login error oVirt_Wiki uses cookies to log in users. You have cookies disabled. Please enable them and try again." I have cookies enabled, and tried with two different browsers. Looks like this happened in the past, and it is caused when disk space is exhausted. Can you take a look?
