Cookies are blocked or not supported login error

Had this problem a while ago on a MU site that I have – Can’t remember exactly what I needed to do to solve the problem, but it involved adding a few lines to the wp-config.php file – trouble is, looking at the file I cannot remember which lines I added, although I have a feeling that it is the below. For obvious reasons I have taken the unique phrases out, but you can visit the URL listed to generate them. Hope it helps –

/**#@+

 * Change these to different unique phrases!
 * You can generate these using the {@link https://api.www.ads-software.com/secret-key/1.1/wpmu/salt www.ads-software.com secret-key service}
 * You can change these at any point in time to invalidate all existing cookies. This will force all users to have to log in again.

define('AUTH_KEY',         '');

Thanks buddy, but after adding the Authentication Keys to my wp-config.php file, I am still getting the same error.

I have tried three different links that I have found and neither of them work.

https://api.www.ads-software.com/secret-key/1.1/wpmu/salt
https://api.www.ads-software.com/secret-key/1.1/salt
https://api.www.ads-software.com/secret-key/1.1

Did you try deleting all cookies frist? May be a problem with the one that is already there, that was created without the keys?

Also, found my post from a few months back, so may hopefully be of use to you.
