I see the problem. Where it says:

<if condition="$show['closethread']">
<script type="text/javascript">
<!--
function get_reason()
{
	if (document.getElementById('ao_oct').checked == true)
	{
		var answer = prompt('What is your reason for closing this thread?', '');
		document.threadadminform.reason.value = answer;
	}
}
// -->
</script>
<if condition="$show['closethread']">

It has <if condition="$show['closethread']"> at the bottom that should be </if>

I fixed that now. I also updated the install file.
