Did somebody find a solution yet?
It seems more users have this problem?
Could it be a problem in combination with Joomfish?

I had the same problem with the germani language. After searching for quite a while I realized, that this might be due to a missing defination in comprofiler/plugin/language/germani/germani.php.

In line 368 I read the following:

DEFINE('_UE_REGISTERFORPROFILE','Bitte melde dich an, um das Benutzerprofil anzusehen oder zu verändern.');

So there is a definition for _UE_REGISTERFORPROFILE but no definition for _UE_REGISTERFORPROFILEVIEW.

What I did to solve the problem was to add the following line in the file:

DEFINE('_UE_REGISTERFORPROFILEVIEW','Bitte melde dich an, um das Benutzerprofil anzusehen oder zu verändern.');

Don't know, if this is a proper solution for the issue but it seems to work out for me.

Hope this helps!
