On May 11, 2018 Producteev will no longer be offering its services. To find out more, please see the announcement blog here: https://community.jivesoftware.com/community/products/producteev/blog/2018/04/09/producteev-services-discontinuing-on-may-11
Therefore, in the mean time, they are providing very little support or effort to bring up the site when it is down.
I recommend switching to Asana, which will allow you to import your Producteev tasks.
we are in the deep trouble. We failed to export our data from Producteev for several companies. now the Producteev site is not accessible. Please provide me the options to retrieve my tasks. it would be much appreciated.
