I accidently had set my credit card processor in the cs-cart settings(not in authorize.net) to test mode and we have had a few orders, is there anyway to recover their info or rerun their cards?
And I suppose you also shipped the goods to your customer… “Your Fired” 
If you are unable to view the CC details within your cs-cart orders pages, and you are also unable to find and capture or re-charge these transactions through your authorize.net control panel, then I would call the customers and kindly explain the situation and ask them for their credit card details so that you can charge them for these orders.
