If you're using Internet Explorer, go to Tools--Internet Options--Privacy. By default, it should be set at Medium, which allows Cookies from the originating website. (ie works with POL). Setting it higher than that risks making websites not work. Setting it lower compromises security.
If you're using Firefox, go to Tools--Internet Options--Privacy. There is a section called Cookies. Make sure that "allow sites to set cookies" is enabled.
Good luck!
