Hi, can you please check if all HMWP settings you have made is intact there. Also try clicking on “save settings” button.
If still doesn’t work, then click on “reset settings to wp” button and then follow these steps:
– goto HMWP Start Tab, select “Medium Privacy – More Compatibility” scheme and save the settings
– goto Permalink & URLs tab and set “rename plugins” option to “all plugins”
Note: Assuming that it’s WP single site and Apache server. Your site’s htaccess file should be writeable. Your new login URL will be http://www.yourdomain.com/wp-login.php?hide_my_wp=1234
