username/password does not work

When you click on any of the courses either on the elementary or the secondary classes page, what should happen is, that your browser will show a new page, with  username/password entry fields.

Username can be anything, depending on yout teacher, but as arule of thumb it is your firstname lastname, like this: Tom Thumb

The Password is always: Fvdes

Please note! The "F" is capital, "vdes" is lower case, no quotation marks.
