Activation link leads to blank page

For some reason the prev post was closed??

I have activated network on my WP site, andhave run into a snag

The activation links sendtwhen registering a new user/blog just leads to a blnk page, and the account is not activated.

I have set up a wilcard in my DNS records (*.domain.com -> 111.111.99.111)
I have added
ServerName https://www.liveview.no
ServerAlias *.liveview.no
to httpd.conf

When creating blogs/users from back-end it works perfectly fine.

Any ideas?
