Moved Drupal 7 site to a different server, can't log in

Question

I recently moved my Drupal 7 site to a new hosting server and I'm stuck at the login page. As soon as I try and log in, I get directed back to the same page, but the URL changes from /user to /user/1, which leads me to believe that I am actually logged in, but I'm not being forwarded to the correct page.

I tried cleaning my cache, emptying the cache tables in the DB but nothing helped.

Any ideas?

EDIT: To make things a bit more clear, I've used the specific server for various other Drupal 7 sites, so I know for a fact that the server configuration is not at fault here.

Answer 1

I suspect your $cookie_domain in /sites/default/settings.php is incorrect.

Try making it match your new domain and ensure there's a leading dot .

$cookie_domain = '.mydomain.co.uk';

Answer 2

Sometimes problems relating to logging in after a site migration can be because mod_rewrite was enabled on the first machine but not the second. A simple way to test this is to use the ?q= URL format (http://site.localhost?q=user) and see if you can log in like that. If that works then you can either disable clean urls from within the Drupal interface, or enable mod rewrite in Apache.
