Files are not cached with woocommerce activated

Hi,

I use WP Super Cache 1.4.4 and WordPress 4.2.2.
Caching works fine.

But if i enable Woocommerce 2.3.8 all caching does not work anymore.
According to the log this is because DONOTCACHE is defined.

I have tried renaming and clearing files woocommerce/includes/class-wc-cache-helper.php and class-wc-session-handler.php but that also does not help.

By the way, all woocommerce files are okay to be cached because visitors cannot add anything to the cart. All products are external/affiliate products.

Can anybody please help me out?
