Hi, please follow these steps:
– in HMWP start tab, set ‘Medium Privacy – More Compatibility’ scheme and save the settings
– in HMWP permalinks & urls tab,
– set “rename plugins” option to “all plugins” and save the settings
– empty out “ajax url” field
Note: Assuming that it’s WP single site and Apache server. Your site’s htaccess file should be writable. After applying above settings the backend login URL will be http://www.YourDomain.com/wp-login.php?hide_my_wp=1234 (you can change secret code “hide_my_wp=1234” from general settings tab)
If you are having any specific issue after applying above settings then please let us know.
