Version1.5.5e
Product Type Book is the only module added.

When a product (either product_general or product_bookx ~ there is one of each type) is selected to add to cart a warning an error has occurred appears.

The content of the error log file is:

I am not sure what to look for in or add to in the database.

Thanks in advance for the help!

OMGosh!

The shopping_cart.php from the product type book mod was flawed (?).
I merged the stock file with the mod and all is ok now.

Sorry - I should have checked this first.
