Hello everyone!

I have tried in many ways but I can not. I would like to override the file:

app/code/community/IWD/OnepageCheckout/etc/config.xml

and remove the node

config > frontend > events > sales_model_service_quote_submit_after > observers > <method>emptyCart</method>

how can i do? thanks

Hi Kangn_namea

Remove the node config > frontend > events > sales_model_service_quote_submit_after > observers > <method>emptyCart</method>

You need to remove the event sales_model_service_quote_submit_after  in IWD Checkout?

Thanks
