Class 'queryFactory' not found on v1.3.9f

An interesting solution?

(Apache v2.2.16 & php v5.3.2)

I remove this line you told me before:
if (!class_exists('queryFactory')) require('includes/classes/db/' .DB_TYPE . '/query_factory.php');

and disable php cache.

Now everything works fine, no more error messages.

So were these problems caused by enabling the php op-code cache?

I'm getting similar errors and the cart as a whole seems functional. I'll have to look into it further tomorrow.

hmmmmm.....

I got this error if I enable APC (php cache).

I've tried this suggestion

and then got another error

PHP Fatal error: Class 'queryFactoryResult' not found in /web/includes/classes/db/mysql/query_factory.php on line 188

What specific problem are you attempting to solve by using APC in the first place? Perhaps your server is underpowered?

I'm fine without apc so far.

Just read some posts and test newer version of apc again to see if they can work together.:cool:
