shopping cart won't save after logout

It was working previously, but after installing a mod recently (I'm not sure which one), the shopping cart no longer saves after a user logs out. Where would I start looking to fix this? I searched the forums for shopping cart save, but can't find any previous posts on this topic. If I knew which files controlled this, I could figure out which mod broke it, and compare the changes.

There are a lot of ways to break the storage of the shopping cart or the retrieval ... :blink:

First ... login and make sure you have an empty shopping cart ...

Next, add something to the shopping cart and move around the Catalog for a few clicks make sure you still have something in the cart ...

Now, go into phpMyAdmin and look in the table:
customers_basket

and see if you see your customers_id with the product that you added ...

Next, log back in to the shop ... do you have anything in the shopping cart?

If you browse the customers_basket (be sure to browse fresh) is everything there or gone?

To see code changes that might affect this can be a problem as there are many ways to alter the original code ...

One thing you might do is get something like Beyond Compare from scootersoftware.com and compare a clean Zen Cart download with your current code and find the changes and see if that helps narrow things down ...

Thank you so much for your in-depth reply.

I can't replicate the problem now. I changed absolutely nothing, but the problem went away. I have no explanation, and it wasn't just me. I was alerted to the fact when multiple customers called in to place their orders over the phone cause the shopping cart kept losing their orders. I tested it all day and kept having the problem described in my original post. Now today when I try to test as you suggested, I can't reproduce the issue.

Scratching my head... Sorry to have wasted your time. Still uncertain if it will happen again, but will test as you described if it does.
