Hi, is “wp-plus” the name you entered in “Change Login path” field in HMWP settings? Make sure that you enter only “wp-plus” there without any backslash “/”
But as you cannot login now, please rename hide_my_wp plugin folder in /wp-content/plugins/ directory. Then you can login with default WP url. After logging in, rename back hide_my_wp plugin folder to it’s original; and then configure HMWP plugin.
If you are having any issue, then please let us know your site’s wp-admin login details & FTP details as private reply so that we can fix it for you. After the login issue is fixed we’ll look into builtwith app issue.
