The Really Helpful Post
If you haven't modified the modifyoptions template, you may replace the entire template with the following one (this template is of the latest vBulletin version as of release: v3.6.7):
<script type="text/javascript">
<!--
function toggle_disabled(status, objid)
{
obj = fetch_object(objid);
if (obj)
{
obj.disabled = (status ? false : true);
}
}
//-->
</script>
