I have the correct list with all the articles of this user.
the error message appears even if I'm not connected with any usernames. it appears as soon as I click on "CB your profile". it does not appear if I click on register.
I've deleted a recreated the link menu and even deleted and recreated the user menu without any luck.
Another strange behavior with Internet Explorer, the profile page is totally messed up :
www.rbbgx.be/index.php/profil and it's not the case with Firefox or Chrome and it's not the case neither when I choose Joomla user profile instead of CB user profile.
The error message disappear and everything is back to normal even with Internet Explorer when I disable Joomla SEF...
