Hi, did you rename wp-admin path in HMWP settings? If so, you might have missed some step during this. Please do these:
1) In “wp_options” table in your database, delete the rows with following “option_name”. Please backup your database first.
– hide_my_wp
– hide_my_wp_undo
– hmwp_ids_installed
– hmw_all_plugins
– external_updates-hide_my_wp
– hmwp_spam_counter
– hmwp_temp_admin_path
2) comment out or remove following line from wp-config.php, if you have added it there previously
define(“ADMIN_COOKIE_PATH”, “/NEW_WPADMIN_PATH_NAME”);
