Hi, please follow these steps:
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”);
You shall now be able to login to backend, and re-configure the plugin again. While renaming wp-admin path name make sure that you follow the on-screen instructions very carefully. Also the new name should not have any special characters and the name should not have been used somewhere else in the site (like page/post slug).
