I have a Drupal site, which has not moved servers, but has changed domain names. I cannot login, using either a login block or example.com/user. I changed the cookie domain in settings.php (base url was never set, btw), cleared the cache and session tables, my browser cookies, and still...nothing.
However, I can still login at the old domain.
If it helps, the old domain was something like example.dreamhosters.com. The new domain is something like example.org. Nothing ever moved on the server end. The only change that was made was that I redirected the new domain to point to the example.dreamhosters.com directory. Any clues?
