Can't load Shopping cart page!

[metadox]

Hi I'm not sure what changes I've made since I have been really configuring the hell out of my Zencart. But I started to test different areas of my site today and I noticed every time I get to adding a product on my site it goes to a blank page. I'm not sure if this has something to do with my configure.php file that I had a problem with or something else. If anyone has any ideas, that would be a big help.

Thank you Aldo.

Fix the problem with some reading. I found the problem was in some bad code in the includes\classes folder by the name shopping_cart.php. After I removed the bad code it worked fine. I believe this happen after I tried a download for some wholesale items. All of this could have been avoided if I would have red the version for the download.
