Content of "title"

[symptome]

In vbwiki-main-Template it says:

<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Expires" content="-1" />
<meta http-equiv="Cache-Control" content="no-cache" />
<!-- end no cache headers -->
<title>$wikidata[pagetitle]</title>
$wikidata[headinclude

Within this title there comes a string at second place ... within each and every wiki-article.
I don't want this second part in the title.
How can I change it?

Thanks a lot!
Marcel

Anyone?
Or is there something else like $wikidata[title] that I could use?
Thanks a lot!
