We encourage Website Express/Pro users to access the product through Business App and the product dashboard. However, if there is a user that requires WordPress Admin access (via www.domainname.com/wp-admin) without access to the product dashboard, you can provide it to them by toggling off the Hide Advanced Login.
To stop hiding this advanced login, navigate to the Advanced Tools section within the Website Express/Pro dashboard.
Next toggle off (it will turn grey) the toggle under Hide Advanced Login.
Once it is turned off a user can log in using www.domainname.com/wp-admin.
