How do you know which style you are using? I'm using whatever is used if you don't have a custom template. Is it template_default or classic?
In Your admin > tools > template selection what you are using as a template is listed. You are using the classic.
Also how do you delete on line from the Information module in the lower left corner. Can you just take out say the discount coupons or the unsubscribe to newsletter?
Also in your admin > configuration > define page status > the discount coupon and others are there>
newsletter requires that you try editing your /includes/languages/english.php file and find the code at about line#138-140
Code:
define('BOX_INFORMATION_UNSUBSCRIBE', 'Newsletter Unsubscribe');
and edit to read(leaving the single quotes)
Code:
define('BOX_INFORMATION_UNSUBSCRIBE', '');
save it and upload to your override folder that you need to create after you have setup one in your includes/templates/your_ folder
Creating your own template & folder based upon the template default file set is something that you should do over using the classic.(serarch here for reasons why). If you like the classic look there are templates for 1.3.x in the download section that look as the classic does or the future_zen template for a different look.
