Hi,

Please follow steps:
– Go to file: app/design/frontend/sns_nazic/default/template/catalog/product/view.phtml find and replace the bellow code:

if ($title = $this->getChildData($alias, 'title')):
	echo $this->escapeHtml($title);
else : 
	echo ucfirst("{$alias}");
endif;

by:

if ($title = $this->getChildData($alias, 'title')):
	echo $this->escapeHtml($title);
else : 
	echo $this->__(ucfirst("{$alias}"));
endif;

‘description’,’YOUR_TEXT1′
‘additional’,’YOUR_TEXT2′
‘tags’,’YOUR_TEXT3′
