Thanks, that's my answer. I was looking in templates instead of looking into the function code itself.
All good now

I still have an issue in here. As this is code related, I'm not so good at finding the reason.

I found in search.php the code

$display['users']["$userid"] = '<a href="member.php?' . $vbulletin->session->vars['sessionurl'] . "u=$userid\"><b><u>$username</u></b></a>";

I want to replace it to point to the correct URL, so I edited it to be

$display['users']["$userid"] = '<a href="$vboptions[homeurl]/user.php?' . $vbulletin->session->vars['sessionurl'] . "iUsername=$username\"><b><u>$username</u></b></a>";

However, when I do that, $vboptions[homeurl] is not understood and instead it is included after the forum root URL.
So the link becomes:
http://forum.mydomain.com/$vboptions[homeurl]/user.php?iUsername=john
instead of
http://www.anotherdomain.com/user.php?iUsername=john

Would you have an idea of the problem?
