Newsletter VIEW_LINK is not working

I have trouble with getting the E-Newsletter plugin to work on a sub site.
Im using SMTP and that works. But the link to view in browser is not working.
In the .po file this default is set up:
View e-mail in browser

But that output this link: x-webdoc://96A2075A-09EF-45F6-B609-340FE407FF84/%7BVIEW_LINK%7D

The mail is here:
