Hi Crew

Having speed issues lately with our site ... so deleted session data ... and
usertrack .... As we have seen discussed here ...
The site is faster but ..Now customers can't log in or order items.

We get these messages in error log:

Attempt to order missing product code:

Hope you can help .. please!
