Super weird. Yes, I see the username and password filled, but it still doesn't allow me to see ClassiPress Admin Demo. All the other demos are working properly though. Just that one.
It is displayed just fine at my end in both Chrome and Opera. You can try with another PC to see if the issue persists.
