Hello,

i created a child portal www.mysite.com/childPortal ,
when I add the token $(OptOutAll, or $(OptOut)  to a newsletter then the link redirect to the Home Page when I click on the OptOutAll-Link or OptOut.
 In Settings, i have configurated correctly the standard opt in email module location.

Also inserting the token $(TrackingImage) is no tracking. 

In portal base everything works fine.

Regards, Mario
