yes thanks, so I guess I'm missing something else maybe.
I have configured several triggers : afterlogin, afterlogout, joomla_onAfterRoute ...etc...
the only time I have the message is after the login. I tried to browse through menus, and specially the logut sounds weird to me as I'm sure that I can see the messase as I have it for login.
attached the screenshot of the triggers, no conditions defined at all.
( btw, I updated everything as well to the latest version in case of, everything is up to date )
thx
