Trying to login to Producteev returns a Error with HTML message for a 404 Page No Found error.https://dl.dropboxusercontent.com/u/859420/Jabanaki/device-2013-06-08-103316.png
This issue is caused by changes to the Producteev API. It seems that the original Producteev API used by TodoToday is not longer available.
Producteev have indicated that a new Public API will be available. When the new API is available TodoToday for Producteev will be updated.
