I am having the same problem, I added the jquery 1.4.2 in my meta.tpl as below, but I'm still getting this error.

  {if $config.UA.browser eq 'Safari'}
    <script type="text/javascript" src="{$SkinDir}/jquery-safari.js"></script>
  {else}
    <script type="text/javascript" src="{$SkinDir}/jquery-min-142.js"></script>
  {/if}
  <script type="text/javascript" src="{$SkinDir}/jquery-fix.js"></script>
  <script type="text/javascript" src="{$SkinDir}/ajax.js"></script>

I also changed these back and forth:

I also changed

  {literal}
<script type="text/javascript">
$(window).load(function() {
$('#slider').nivoSlider();
});
</script>{/literal}

to:

  {literal}
<script type="text/javascript">
$(window).load(function() {
jQuery('#slider').nivoSlider();
});
</script>{/literal}

I'm so lost with this one. I never imagined that adding a little bit of javascript to X-Cart would be such a headache. If anybody can help me, I would greatly appreciate it.
