iView Personalizations

Hello,

I made some Personalization changes to the Dev. Portal which worked fine , I then transported them to the QA Portal ,the changes are not visible there. I looked at the below thread:

So where can we change the User Language for Portal.

Also, when I manually tried to made the same Personalization Changes in QA Portal with Content Admin. , the changes are not getting reflected.

Any help would be highly Appreciated.
