WordPress Login 404 error after renaming wp-login.php

Hi,

So I had my site on a webhost where I renamed wp-login.php to something else and all worked fine.

The problems first arose when I transferred my site to a different webhost. I copied my database, wp-config etc etc and my site is accessible including wp-admin (when logging in from wp-login.php).

As soon as I changed the login url (using iThemes Security Plugin), the new login URL works fine but as soon as you login, I get something like “wp-admin has been disabled”.

Note – I have tried disabling all plugins, done a fresh install, deleted htaccess. I have also tried other plugins to rename the login URL with no luck.

Please help
