Hello
You could try rearranging the sidecolumn modules and component are in your templates main.php. Locate the following in ../templates/j51_evolution/php/layouts/main.php..
<!--Side Columns Layout-->
<?php if ($this->countModules( 'sidecol-a' )) : ?>
<div id="sidecol_a" class="side_margins">
<div class="sidecol_block">
<jdoc:include type="modules" name="sidecol-a" style="mod_standard" />
</div>
</div>
<?php endif; ?>
<?php if ($this->countModules( 'sidecol-b' )) : ?>
<div id="sidecol_b" class="side_margins">
<div class="sidecol_block">
<jdoc:include type="modules" name="sidecol-b" style="mod_standard" />
</div>
</div>
<?php endif; ?>
Cut this code and paste it just before the following towards the end of the same file...
<div class="clear"></div>
<!--End Content width and show component area-->
