Hi, it seems like you have missed something there while trying to rename wp-admin path. Please follow the steps below:

In “wp_options” table in your database, delete the rows with following “option_name”:
– hide_my_wp
– hide_my_wp_undo
– hmwp_ids_installed
– hmw_all_plugins
– external_updates-hide_my_wp

You shall now be able to login to backend. And to change wp-admin path name you’ll need to follow the on-screen instructions very carefully. Please follow these steps:

– in HMWP Start Tab, select “Medium Privacy – More Compatibility” scheme and save the settings (assuming that it’s Apache server and htaccess file is writable)

– in Permalink & URLs tab set “New wp-admin Path” field to “NEW_WPADMIN_PATH_NAME” (a new window will open with the instructions)

– add following line in wp-config.php, before require_once(…)
define(“ADMIN_COOKIE_PATH”, “/NEW_WPADMIN_PATH_NAME”);

– you’ll also need to update your .htaccess file (if it’s not writable) by adding following line before ‘RewriteCond REQUEST_FILENAME} !-f’:
RewriteRule ^NEW_WPADMIN_PATH_NAME/(.*) /wp-admin/$1 [QSA,L]

– click on “I did it (login to new dashboard)” button.

If it’s still the issue then please let us know your website’s wp-admin login details & FTP details (as private reply), so that we can look into it further.
