I am using Wordpress 3.6, the latest version.
When I access login page for admin URL like
www.example.com/wp-admin and I enter the username and password, Wordpress redirects me to the same page.
But when I try to access using
www.example.com/wp-login.php then it works perfectly.
When I try to login using wp-admin, I am redirected to
www.example.com/wp-login.php?redirect_to=www.example.com/wp-admin%2F&reauth=1 strange URL.
I Googled it and found interesting thread on wordpress.org: http://wordpress.org/support/topic/wp-admin-suddenly-not-working, this thread seems inactive and old. I tried to apply all the suggestion but doesn't work
How to fix this issue? Is there any plugin for that or is there any error in some of the plugins?
Update I am using Subdomains and my site is accessed at www.subdomain.examplesite.com. And i am using windows hosting with IIS server.
