I am using WP 2.9.2 and I just enabled FORCE_SSL_ADMIN for my site. After I enabled the setting, WP correctly started to redirect logins to HTTPS. I was able to bring up the wp-login.php page over SSL.
However, when I try to login, I get the following error message:
I've tried two different browsers, wiping the cookies and cached data on both and still, it doesn't work.
Can anyone help me please?
