Portal Logon page

portal logon page is in different language ( say German )
The cotent is in another language ( English )

REASON:
1.There is a user called J2EE_GUEST and the user's langaage must have been set to a
language -German ..you can remove this language selection from 'user administration'

2.Otherwise the browser default language might have been set.

How is the language preference calculated by the portal.

In Visual composer UNION does not work as expected
Fact:This works actually as exected
The expectation is wrong !!It will not combine all the fields from different
data services and give you a collective result. It will only combine data from "SAME DATA TYPE" .

The expectation of all fields should be included is someting lik JOIN operation in DBMS terms and is not available in Visual Composer.
