wp-login.php redirects to newlogin__.php

Hi guys,

Last week I posted a topic about the custom login page redirecting to WP login page (see http://wordpress.org/support/topic/custom-login-page-redirects-to-wp-login-page?replies=12)

That problem got fixed by
1. Renaming wp-login.php to old-wp-login.php
2. Renaming newlogin__.php to wp-login.php
In my FTP file manager

Right now I got a similar problem:
When people try to login through http://www.onlinetradinguniversiteit.nl/wp-login.php

They will get redirected to http://onlinetradinguniversiteit.nl/newlogin__.php

(No matter if they fill in the right password or not). Which is a page that doesn’t exist.

Almost all users use our custom login on http://onlinetradinguniversiteit.nl/ which works just fine, but I also would like the http://www.onlinetradinguniversiteit.nl/wp-login.php to work the way it should, because some users use that link.

Any suggestions?

Kind regards,
Tim
