// here's the error from firefox's debugger
uncaught exception: [Exception... "Could not convert JavaScript argument arg 0" nsresult: "0x80570009 (NS_ERROR_XPC_BAD_CONVERT_JS)" location: "JS frame :: http://localhost/testsuite/media/js/jquery.min.js :: anonymous :: line 115" data: no]
here's the html markup
<div id="wrap">
<div id="header">
<?= $header ?>
</div>
<div id="content">
<?= $content ?>
</div>
<div id="sidebar">
<?= $sidebar ?>
</div>
<div id="footer">
<?= $footer ?>
</div>
</div>
EDIT
I was using Jquery 1.4.1 when this happened. Switched back to 1.3 and everything went back to normal.
