Login/Registration Problem

[JustJo]

Hi, I am new to Zen Cart and most likely I am not doing the right thing, but each time I try to test and go to the Checkout, I get an empty blue screen. I am sure it's a registration problem because I am testing as a guest, but the problem is that when I try to Login, I get the same empty blue screen (.../index.php?main_page=login)

My store will be at http://www.jgarbellotto.com/store and it's not ready yet but I have added just three photos to test (this is not what I will sell!), but if someone wants to take a look at what I am saying I would really appreciate any help I can get.

You are using a very old version of Zen Cart and should upgrade to v1.3.6 ...

You also have Products in the Top Level Category and Products should always be in their own Category ... this can cause issues on searching and prices etc.

You may also have corrupt files or errors in your files causing the errors ...

This may be a good time to start with a clean install and database ... as you do not appear to have a lot added to your site at this time ...
