Unable to change advance settings

I recently disabled the page block cache in an effort to resolve an issue with the calendar not appearing on forms (including join).  It didn't help so i thought I would see whether some of the other caching might be affecting it.  I unchecked caching for html, js etc.  But to no avail.  Unfortunately since I did that I cannot get back into advance settings to re check them all.  The arrow on each section in advanced settings is not visible and I cannot expand any section.

Any ideas?

Thanks to "Dolphin Jay" for this workaround

Open /templates/base/scripts/bxbaseformview.php  scroll all the way to the bottom of the page and you will find this function:

function getOpenTbody($aAdd = false) {
if (!$this->_isTbodyOpened) {

if ($aAdd and is_array($aAdd))
$sAttrs = $this->convertArray2Attrs($aAdd);
else
$sAttrs = '';

$sCode = "
<tbody $sAttrs>\n";

$this->_isTbodyOpened = false;

return $sCode;
} else
return '';
}

Now everything in the settings advanced settings will be opened on page load rather then on down arrow click.   If it still does not work for you then i would say you have something wrong with your java on your pc or there is a odd server setting missing.

Once I was able to re-check all the caching all my problems were resolved.
