Impossible to "manage comments" from the Joomla Administrator console with a user having the "administrator" rights. Each time that I try it I have the following error: "Vous n'êtes pas autorisé(e) à accéder à cette ressource.Vous devez vous connecter. " (french message). In english that message could be "You aren't authorized to access this ressource. You must be connected.

The same operation with "the super administrator" rights work. However I cannot give it to the person responsible to manage comments.

Could you help me to find a solution?
