So it is working when the customer HAS previously placed an order? YES

The users can register directly on the site by clicking on the register button and filling out all required fields address, phone, etc, etc. Or the user can purchase products with out register using COWOA Updated and Combined "Guess Checkout". I have made no changes with the customer address book unless guess checkout query has conflicted with admin new orders in the DB. I also have Ty Package Tracker installed but I merge the files careful so there is no conflict between those 2 modules "Admin New Orders."

Can you compare your version of "query_cache.php" with the stock one in Zen Cart 1.5.1?
I did compare the files everything seems collect.

How are the customers being added to Zen Cart? Do the customers have an address book entry? Have you installed any modifications to the default Zen Cart customer signup? Have you made any changes to the customer / address book database tables?


This error message is related to the Zen Cart SQL cache (which is not utilized by Admin New Orders). Have any modifications been made to "Admin New Order"? Can you compare your version of "query_cache.php" with the stock one in Zen Cart 1.5.1?

Note: I've only seen that message in a few cases (completely unrelated to Admin New Order). Case 1: Zen Cart was upgraded from a previous version and query_factory.php was skipped. Case 2: The "query_cache.php" file is not the one from the stock Zen Cart 1.5.1. I've seen a few people trying to merge the "Query Cache" plugin into Zen Cart 1.5.1 (it is not compatible or needed). This will cause issues.
