Magento 1.7
I am unable to log into the admin backend all of a sudden - it's been fine for many years!
Chrome: If I go to www.mydomain.com/admin I get sent to mydomain.com without and error message or login screen
Firefox: Same behaviour except the URL I see is: http://www.mydomain.com/index.php/admin/index/login/key/5e3e7decd5896ea483256d0509b4e55a/
Firebug in Firefox says: http://www.mydomain.com/index.php/admin/index/login/key/5e3e7decd5896ea483256d0509b4e55a/ 404 error not found
I can log in as a customer though
Any help would be very gratefully received!
Thank you
