Product page doesn't show footer, sideboxes and additional images

Hi folks,
I've been installing templates and plugins to our new website, but i didn't notice as I may have overwritten some of the template files. Now my product page doesn't show neither the footer, right sideboxes or additional images.

my debug file reads this:
[07-May-2012 11:01:04] PHP Warning: Invalid argument supplied for foreach() in /home3/belchous/public_html/includes/templates/theme600/sideboxes/tpl_categories.php on line 20.

It doesn't make sense to me because i'm not using this template (mentioned above).

Website: http://www.belchousa.com

I'd appreciate any help!
Thanks in advance.

Zencart loads all stylesheets in the current template's css folder whose file names start with 'style' and have the .css extension. Try removing stylesheet_tm_old.css.

I deleted all _old css files.. still no luck:(

After i deleted tpl_modules_additional_images.php file the missing parts reappeared.

Now i have to find out why the site is trying to load different css files.
