When a client tries to make an appointment for today (11/13), today is grayed out and none of the appointments are available.
We offer appointments until 6:30 PM and it's only 2:20PM now.
This seems like a near relative of the problem you fixed last time. Everything has been working fine since then.
I've activated support access for you:
Support access is ACTIVE until November 16, 2014 10:18 pm
