Customer registering problem

[quickchick]

hello- I am new here, and I am not a web designer. My web site designer is MIA and I have a problem with OSC.
Customers are unable to place orders, they are able to register the first time to receive a coupon, but when they go to place an orderand sign in, they are then sent back to keep trying to log in. Can someone please help me to fix this problem.
Thanks in advance-

Leslie

if thats the case, it could b as simple as making sure you http n https cookie domains are correct.
