If you are a Klout user you should be aware that this platform is being shut down as of today, 25th of May 2018 - see Klout Shuts Down. Therefore our Klout Web Connector will no longer work and it will be removed from our connector bundle from June onwards. If you continue to try to use the Klout Connector you will get an error - this is not a Qlik issue and you can prevent the problem by removing Klout data loads and connections. If you don't use the Klout Connector you will be unaffected.
Thank you for choosing Qlik software, if you have any questions please don't hesitate to contact Support.
