Dataset query works in preview but not on live site

The site name.
Blueskye-International

• The site URL.
https://www.blueskye-international.com

• The page that your question relates to or where the elements is located / issue is occurring.
https://www.blueskye-international.com/search-for-an-expert

• The element name which you are having trouble with.
tblShowConsultants which is connected to dataset1

• What exact steps you performed (what set up you have applied) while trying to achieve the desired result yourself.
The query works fine when in PREVIEW mode but when the site goes live no data shows.

Anyone had this problem?
