Hi
You can edit layout file and move block example in this file for default layout
/templates/ja_purityIII/tpls/default.php
change order from :
<?php $this->loadBlock('header') ?>
<?php $this->loadBlock('spotlight-1') ?>
<?php $this->loadBlock('mainbody') ?>
<?php $this->loadBlock('spotlight-2') ?>
<?php $this->loadBlock('navhelper') ?>
<?php $this->loadBlock('footer') ?>
to :
<?php $this->loadBlock('header') ?>
<?php $this->loadBlock('navhelper') ?>
<?php $this->loadBlock('spotlight-1') ?>
<?php $this->loadBlock('mainbody') ?>
<?php $this->loadBlock('spotlight-2') ?>
<?php $this->loadBlock('footer') ?>
