wp-login.php is not working…

Hi guys,

Two weeks ago I posted a topic about the custom login page redirecting to WP login page (see http://ww.wp.xz.cn/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

But now I got a new 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 or does not work.

Do any of you guys have suggestions for me?

Thanks,
Tim
