I'm having a problem with the guest login. The Moodle version in use is 1.8.1+. We have direct links on the Moodle front page (made with html -block), which takes the user to the course and directly to the forum in course. The problem is that when the guest user clicks the link, the login window appears and nothing happens. For example if the user clicks login as guest button in the login window the login window just stays on. The link created in the html block is correct.
The interesting part is that in the settings the guest user option is set in a way that the login window shouldn't even appear. The guest autologin setting is on. The course settings are also ok, allowing guest access to the course.
Any ideas on what the problem would be? Thanks in advance for any information.
