Depending upon the theme you are using:
In qa-theme.php
If the sidepanel function does not exist add this:
function sidepanel()
{
$this->output('<div class="qa-sidepanel">');
$this->widgets('side', 'top');
$this->sidebar();
$this->widgets('side', 'high');
// $this->nav('cat', 1);
$this->widgets('side', 'low');
$this->output_raw(@$this->content['sidepanel']);
$this->feed();
$this->widgets('side', 'bottom');
$this->output('</div>', '');
}
If the sidepanel function already exists add // in front of $this->nav('cat', 1);
