I have just discovered that all my wordpress sites have the same fault: The login page does not resolve.
Instead if I type in site.com/wp-admin
or site.com/wp-login I get a 404 error page.
If I type in site.com/wp-login.php I get 'The page isn't redirecting properly'
I have tried searching G for a solution but none found.
So, any wordpress experts here that can shed some light on this problem
Many thanks in advance
