A few more details would be appreciated :-S

1) Have you recently upgraded ?
1a) If not then have you recently changed anything to do with your server or setup ?

2) Do you own domain.com ?
2a) If you don't then could you please post a link to your blog?

Well, I upgraded yes from v1.10.3 to v2.4.6. Then I deleted everything and did an install from scratch of v2.4.6
Same thing

I deleted the cookie for the site.

That didnt solve it.

The install created all the tables and the blog displays.
See catherine.mjl-it.com

But I just cant login to admin or just to identify myself.

It seems to have been a cookie problem
I only deleted the cookies for the sub domain.
On deleting the cookies for the domain, it works

When I upgrade, i normally change $instance_name in /conf/_advanced.php ... logs every bugger out but cures loads of shit when they login again ;)
