I can't log into the Wordpress admin on my site (http://planestrainsandplantagenets.com/). I was able to log in up until around an hour ago, and then it suddenly began booting me back to the login page.
I haven't added any plugins.
The only thing I have changed is moving the URL from "http://www.planestrainsandplantagenets.com/" to "http://planestrainsandplantagenets.com/" - I've tried to login with both URLs and neither now works.
Can't access anything at all - I enter my user name and password and it just sends me back to the login page.
