Just be careful, it can be annoying.
When accessing your WP-ยต, you can either use wp-login.php or enter /wp-admin/
If you are not authentified, the system will work correctly. But if you are authentified, it will try to reach wp-admin/ and it will fail.
If you want to patch it:
1. Go to your wp-login.php file in your host.
2. Go to line 213, and make this change:
$redirect_to = 'wp-admin/';
$redirect_to =
ABSPATH .
'wp-admin/';
It will work correctly again.
