After login in site and go to userlist page when I click on my name link it fails and redirect me back to userlist; but if I click on the rest of the row (not in the name) it works! and go to user profile page.
It only happens with the link of user that have logged-in, the rest have no problem in link.

Any help please? Isn´t it weird??

It works fine on my site. Are you using SEF? If so, which one?.... You can disable it and see if the link is correct without it. If it is, check with the developer to see how to correct the link. If not, please give more information, such as a link and test login, along with Joomla, PHP and Database versions. Thanks

No still not using SEF. I will use it but not now.

Joomla 1.5.8 - CB 1.2RC3 - PHP 5.2.6

1)You can go to www.zatozte-ondarroa.com
2)login as: alai - merkatari08
3)go to userlist page www.zatozte-ondarroa.com/index.php?option=com_comprofiler&task=userslist&listid=4&Itemid=62&lang=eu and click on ALAI user's name. You´ll see it directs you back to userlist but if you click on the rest of the row it works.

Sorry to say that it didn´t work. I applied fix and everything works as before
