This question already has an answer here:
I'm having an issue trying to use DHL plugin in Magento 1.9.
I have introduced all the fields with the DHL information but when I'm trying to buy an item it says:
"This shipping method is currently unavailable. If you would like to ship using this shipping method, please contact us."
I've found that I need to switch from Test mode to Live mode but I can't find where I can do that (I'm using production URLs given by DHL).
