How to edit contents of shortcode?

My shortcode is [userlog] in My Accounts page under Products Page.

For some strange reason during login at my domain, it is calling https://www.mydomain.com/wp-login.php instead of https://www.mydomain.com/wordpress/wp-login.php.

Does anyone know the reason for this? M

Not sure if Payment Gateway is related to this, but I have set it to test gateway.
