Andrey again thanks for your help :)
I recompiled the en language for orca but how can i compile groups/orca?

And another question.
What is wrong in templates/base/scripts/BxBaseCmtsView.php
in line 41:
function getComments ($iCmtsParentId = 0, &$iOverflow = null, &$iCountTotal = null)
It looks like something is problematic here and it is not waiting those 3 variables...
I had to commentd this function and function getCmtsInit () to go on after the new installation. But this is see more creating problems in ray.
