New Multisite Confirmation Email

Hi there,

The confirmation-email which new users receive when signing up on our multisite platform is missing the following info:

1. The site name which is generated from SITE-NAME in the system
2. The Team Name on the last line of the email

And the message title still includes the word "Wordpress" even with the ultimate branding plugin enabled.

In multisite settings, the network name is inserted and the "welcome email" field includes the "SITE-NAME" field.

I did have "custom email from headers" enabled in the ultimate branding plugin, and which I then disabled, and then resaved the network-settings and which has not solved the problem.

The sites created do include the site-name in the header-area.

How can I rectify this situation?
