Hi Zen Masters,
I have read all kinds of threads with this type of problem but the others seem to have other problems as well. Everything else in my store appears to be working great. The Orders are processed and receipts are generated and all of the order info is input to my mySQL database. I can use that information by querying specific items that I need. The problem is, my customers can't view their order history and I can't either on the Admin page.
I'm not exactly sure when this problem first occured, but was told by one of my customers a few weeks ago that they couldn't see their history. I have been busy with the business and this is our high time, so it's difficult to shut down the store at this point. I did take out all of the override folders, named "snowstar" to see if those were the problem. It didn't change anything so I put them back.

I am using version v1.3.9h which I downloaded as a new installation in June 2011.
I have QBMS credit card processing. All of the "Order Total" modules are turned on except the C.O.D.
The customizing that I have done is mainly cosmetic. My logo and colors. I have also customized the email info and added instructions to my order pages.
My website is, http://www.snowstar.us and a direct link to my storefront is, http://snowstar.us/Zen/index.php.
My host is LinkSky. If you need a link to them, I can supply that. They have all up to date versions of php and mySQL. Php version 5.2.16 and MySQL Version 5.0.92-community. It uses Apache version 2.2.17 and is on a linux operating system.

As I mentioned before, the store works great and I don't care if I can't see the order history in the admin area because I mainly gather the info directly from the database. I just would like my customers to be able to view their history. If you need more info, I'll be happy to supply whatever I can.

Thanks for your time
