Sorry, i forgot this text.

For Multilanguage modify the file includes/template/template_default/sideboxes/tpl_news_scroll_box.php on line 177

Overwrite
$content .= '<a href="' . zen_href_link('news_archiv', '', 'NONSSL') . '">News Archiv</a>';

with
$content .= '<a href="' . zen_href_link('news_archiv', '', 'NONSSL') . '">' . TEXT_LINK_NEWS_ARCHIVE . '</a>';

Repeat this on line 195

Now open the file includes/languages/english/enxtra_definitions/news_scroll_box_defines.php

Add at the the end of the file before the ?>
define('TEXT_LINK_NEWS_ARCHIVE', 'News Archive');

Repeat this step for all Languages you used in your shop.
