[forum] dead links into mail notifications

Hi,
when receiving mail notifications related to new answers or subjects into this forum, I see that the 3 links (Link to post, Link to topic, Link to reply) are dead links leading to following 404 error :

[quote]Page not found
Error 404

gphilippe, the requested page does not exists.[/quote]

I get this from several messages I tested (even on messages which worked if I remebmer well) so I conclude something is broken on the website.
