Hi,

Yes, to solve this prolbem, please go to the file app\design\frontend\default\sns_korion\template\catalog\product\view.phtml, find and replace the code bellow (uncomment):

<!--<?php if ($this->getChildHtml('additional')):?>
                    <li class="item-tabulous"><a href="#sns_tab_additional"><?php echo $this->__('Additional Info') ?></a></li>
                  <?php endif; ?>-->

By:

<?php if ($this->getChildHtml('additional')):?>
                    <li class="item-tabulous"><a href="#sns_tab_additional"><?php echo $this->__('Additional Info') ?></a></li>

The same with the code bellow:

<!--<?php if ( $this->getChildHtml('additional') ) : ?>
                    <div id="sns_tab_additional" class="tab-item">
                        <div class="collateral-box">
                            <?php echo $this->getChildHtml('additional'); ?>
                        </div>
                    </div>
                    <?php endif;?>-->
