Hello,
I have this annoying problem: when I want to unsubscribe in the mail followed by a discussion, I have every time the same error message: "Authorisation code mismatch. Are you Accessing this function Correctly? Please go back and try again. "
This tells you something? What to do?
With all my thanks. Friendship.

So you get automatically mails when someone sends a message in a discussion you posted a message in? You can switch this best off like this. I suppose your language in the forum settings is French.
You first have to go to "Configuration" (or in English User CS).
Then under "Votre Profil" you will see the function "Options"
If you click on it, you see a screen with somewhere in the left middle Messagerie et alertes. A bit more down you see "Mode d'abonnement aux discussions par défaut." Here you can choose something, choose Ne pas s'abonner.
Then Save these setting. That should do the trick.....
Sandra, thank you very much for the quick response!
I know this parameter, but my concern is somewhat different from what you explain: I can unsubscribe at certain discussions, not all notifications mails I get! Just for old things I do not want to follow.
So in the mail I receive, below the link to go into the discussion, there is a second link that allows you to unsubscribe from this disussion, and that's where I have this error message arriving on Forum!
Thank you again for this help, and for any help, friendship.
Note: I use good French as a parameter.
Hmmm..... then maybe Robert can answer this question for you.

It is very good !
Merci beaucoup ! Thank you ! Viele danke !
