Ahh whoops. Not enough coffee yet today
So the line-height and font are getting set to 0 (inheriting from theme.9.css in your template). You can add something like the following to fix it:
input.sclogin-username.input-small, input.sclogin-passwd.input-small {
font-size: 14px;
line-height: 14px;
}
As always, we'd suggest adding your own theme with your custom CSS changes to SCLogin so you don't lose any changes on upgrade. Instructions can be found

.
Let me know if you have any trouble with the above CSS.
