nice for Woocomerce

1) I see a 404 page not found while clicking the delete account tab?

You might need to refresh the permalinks. Navigate to Settings->Permalinks and Save.

2) I accidentally deleted my own account. I am the owner of the site.

There is no way to recover the deleted user because the data is permanently deleted from the database. If you’re locked out of your own site, you’ll need to create a new user and get access to the site.

3) How to add the delete account option in the PHP template file?

Using the code snippet below:

<?php
do_shortcode( [‘wp_frontend_delete_account’] );
