OK , fix is up , now , I fund out that this happens only on 5.3.0 -5.3.3 , this was php parse_ini_file() bug and seems fixed from 5.3.3
due to this we cannot say that it is grid bug but the php bug , so we will not change the grid version.
Since we cannot know what php version you will have, we updated all 1.6 templates/demos ,
the fix is very simple ,
NO ACCOUNT YET?
than go to
open all 4 files you see and find the text call you previously changed , simply add underscore where you see the empty space
