please use WP site_url() instead of domain root when linking in admin area

After upgrading to 4.0.0 the below message appears on dashboard:
“Your store is configured to serve digital products using “Redirect only” method. This method is deprecated, please switch to a different method instead.”

the link provided points to the root of the domain

, which in my case results in failure, because the shop is installed in a subfolder and there is anouther wordpress site in the root of the domain ??
