I am using mod_neorecruit_latest_offers in popup mode. When users using this module popup windows are white color with black text and without any design, also in error log i found ---

[Sun Oct 12 13:19:39 2008] [error] [client x.x.x.x.x] File does not exist: /home/xxxxx/public_html/404.shtml, referer: http://www.xxxx.xx/index2.php?option=com_neorecruit&task=offer_view&pop=1&page=0&id=30&Itemid=142
[Sun Oct 12 13:19:39 2008] [error] [client x.x.x.x.x] File does not exist: /home/xxxxx/public_html/templates/system/css/template.css, referer: http://www.xxxx.xx/index2.php?option=com_neorecruit&task=offer_view&pop=1&page=0&id=30&Itemid=142


Imagine - every visitor who click on this module offer generate this 2 errors
First one is that there is not a template.css and other one that there is not a 404.shtml

How i can fix it???
