Access sub-directory WordPress site admin

Hi,

I have installed the plugin on my main directory (www.example.com) and changed the default admin path (www.example.com/login/) which works fine.

Now I have another wordpress site at (www.example.com/test) this does not have Hide-wp installation at all and unfortunately I am unable to login to this site. Though the site works on frontend.

I have tried all these links to login.
-www.example.com/test/wp-admin
-www.example.com/test/login.
But I cannot login without deactivating the plugin from the main directory.

Any help would be appreciated.
Thanks,
Megan
