Joomla 1.7 "Notice" error

In index.php of the template replace:

<?php if ($this->getBuffer('message')) : ?>
<div class="error">
<h2>
<?php echo JText::_('JNOTICE'); ?>
</h2>
<jdoc:include type="message" />
</div>
<?php endif; ?>

with

<jdoc:include type="message" />

In some templates this change is in container.php which is inside template_name/include/blocks
