Right column of 3 column layout missing after upload

[resurgem12]

I have a local site running on XAMPP that I am happy with.

I've uploaded the site to our remote server, nearly everything is okay (couple of URL's needed changing) apart from the right column of the 3 column layout is missing.

Magento Version 1.9.2.4

Please see images below of the issue.

This is happening due to a lack of space. I have a solution although it will make it appear messy, you need to edit following css. If you remove the margin-left attribute from the element .std ul li. You can find this in CSS file line 2056. This will remove the margin from each item and make enough space for 6 to fit but it will make appear messy as each item will be extremely close to each other.

I've tried changing the main page width and the .span3 attribute which deals with the width of the left and right column.

This didn't work...

I'm struggling to find the CSS your suggesting, I couldn't find it in the styles.css or the responsive.css files
