Cannot change the Forum's Location

I'm using both the US and the German Forums in case I need help with issues regarding Norton 360.

When I visit the German forum's home page (http://de.norton.com/community) I login in using my German credentials. 

After login in, I am automatically redirected to the US version of the forum. Anny attempt to change the location of the country (or the langue / country for which the forum is intented) fails, als the selection window appears not to respond (see attached image)
