Thank you for the site upgrade. I am a bit disappointed that with such a major upgrade that active_order_count for the privateInfo API call wasn't fixed. It has never worked and it is looking like it never will.
It's already fixed.

No, sorry. It isn't.
From site:
BC/BTC Buy 0.00002079 1000 0.02079 0% Active
privateInfo API call response:
{"status":"success","data":{"active_orders_count":"0","perms":...,"server_timestamp":1405966944}}
OrderHistory API call with active_order == true:
{"status":"success","data":[{"amount":"1000","timestamp":"1405966662","id":"1363994","rate":"0.00002079","status":"Active","pair":"bc_btc","type":"Buy"}]}
