Hi, it seems like you have tried to rename wp-admin path, and missed something there. 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 there previously:
define(“ADMIN_COOKIE_PATH”, “/NEW_WPADMIN_PATH_NAME”);
Let us know!
