New Post: login

Hi
I copied a backup of a composite C1 website to a new server. The site runs without any problems but I am not able to login to edit content.. I followed the suggestions in article

https://c1cms.codeplex.com/discussions/391080

(deleted users and restarted app)

But when I go to the login page (.../Composite/Login.aspx) i give it credentials but I don't get into the Admin area just back to the homepage of the site?

Suggestions ??

Regards

Meir
