I checked and set same permissions for two groups but could not solve that.
Honestly I am checking on two 2 demo sites, a site updated from xen 1.5 {1} to Xen 2
and a site update by importing pure Xen 2 source from a Xen 2 forum {2}.
And site {2} is showing as picture (1) which I wanted. I don't know what to set and make site {1} work as {2} now.
