Article Manager displaying incorrectly

[AshRa]

I'm new to OSCommerce (3 days old) and have been asked by somebody to add a few contributions to their site. WYSIWYG and HeaderTags were fine but i'm having a problem with Article Manager

 

I can create articles from within admin but there is some problem viewing them.

 

I have added the require(DIR_WS_BOXES . 'articles.php'); to the bottom of /includes/column_left.php and on the index page I am only getting HTML down to the bottom of the 'Articles' header in the left hand nav.

 

Also I don't know if it is my imagination but the page seems to be loading twice.

 

The product page displays fine with the list of my test articles, but when I click through to article.php the same thing happens (but I don't even get the 'Articles' header)

 

I hope somebody can help...
