I'm having an odd login problem. At first I noticed that when I tried to log into the admin CP, the login page would simply refresh back to the login form. If I then refreshed the page through my browser, the admin CP would appear. But if I didn't, I'd just get a blank login form again. Then, a user told me that she was having trouble logging in. She said the page refreshed but she still wasn't logged in. Something is awry. Any ideas?
