The problem is that you are loading this script TWICE and in the WRONG location:
<script type="text/javascript" src="http://www.viking.ee/veeb/wp-content/plugins/scripts-gzip/gzip.php?js=wp-includes%2Fjs%2Fl10n.js%3Fver%3D20101110%2Cwp-includes%2Fjs%2Fjquery%2Fjquery.js%3Fver%3D1.4.4%2Cwp-content%2Fplugins%2Feasy-fancybox%2Ffancybox%2Fjquery.fancybox-1.3.4.pack.js%3Fver%3D1.3.4%2Cwp-content%2Fplugins%2Feasy-fancybox%2Ffancybox%2Fjquery.easing-1.3.pack.js%3Fver%3D1.3%2Cwp-content%2Fplugins%2Feasy-fancybox%2Ffancybox%2Fjquery.mousewheel-3.0.4.pack.js%3Fver%3D3.0.4"></script>
I see it once completely at the top right after <head> and once in the body section right after <header id="branding" role="banner"> ...
Remove that last one and move the first one to right AFTER the part
<script type="text/javascript">
head.js("http://www.viking.ee/uusleht/js/jquery-1.4.4.min.js","http://www.viking.ee/wp-content/themes/veeb/js/jquery-ui-1.8.7.custom.min.js","http://www.viking.ee/wp-content/themes/veeb/js/jquery.jBrowserBookmark.min.js");
