Can't login with Nokia 6300

I am not able to fill in my password on the mobile site of Moodio ( m.moodio.fm ) since there is no box available to do so.
I'm using a Nokia 6300.
The box for filling in my emailadres is available.
When I check the site with Opera I can see that the box for the password is available.
I'm using the default browser in the Nokia 6300.
Can someone help me out, or maybe can make an adjustment to the login page so that the box is available for Nokia 6300 as well?

I#ve got the same problem

So more users seem to have this problem. Maybe someone from moodio can fix this login?

So there are several reports of people who can't login with their Nokia 6300 phone.
Can someone from the moodio support team please fix this???
