CRS-REP-1005 issue

[lahdeb]

Hello  everyone

I need your help regarding an issue that I have on all my reports received as an XHTML link by email , when I click on the link I have the following error :CRS-REP-1005 (see attached screenshot )

I have the same error when I try to open the report by clicking on a saved version on the portal !
It is indicated in IBM Forum that it is a rights issu on  data folder of the Cognos instalation on unix , but I can guatantee that there were any rights changes on this folder since a while;

Thank you very much for your support
