CUNY Academic Commons

Hi, I need to map plhebert.com to my wordpress blog (plhebert). I've set the A name records and added the name to the domain mapping settings in Wordpress. Now, I cannot access the page nor the dashboard. I've had this happen before when I was setting up meetalexander.com and it was fixed relatively quickly, but I wasn't given an explanation so I'm not sure if I'm doing something wrong or if there's just something that needs to be done on the Commons admin side. Thank you!
