woocommerce and domainmapping

Are you using any caching? Make sure everything is set correctly, you can read more about it here https://docs.woothemes.com/document/configuring-caching-plugins/

Is this a MultiSite? If it is WooCommerce needs to be activated on a site by site basis, it can’t be network activated

I dontt have caching ??
