Error on "Member of" link in Details view

[Percy]

I have created a Consultant group and added a member to it. When I click the

Member of: Consultant

the system displays the following error.

The requested URL /addressbook/indexgroup=Consultant was not found on this server.

But the drop-down group list works.

Do I need to edit anything on the code to make the "Member Of" link work?

Found solution for my problem

Edit include/view.w.php (bottom part)

line...

echo "<a href='./index${page_ext_qry}group=".urlencode($g['group_name'])."'>".$g['group_name']."</a>";

should be written as

echo "<a href='./index.php?${page_ext_qry}group=".urlencode($g['group_name'])."'>".$g['group_name']."</a>";

This worked for me
echo "<a href='./index.php?group=".urlencode($g(['group_name'])."'>".$g['group_name']."</a>";

Unfortunately it didn't work for me and I got the error below.

Member of:

Anything else that I could do to fix it
Thanx in advance.
