I am experiencing "Incorrect signature" responses while requesting any Lists API XMLs.
<hash> <request>/tweetvisor/lists/subscriptions.xml</request> <error>Incorrect signature</error> </hash> I tried various methods, with no success: POST, GET, HTTPS (default), HTTP. It only happens to Lists API calls, all other released API calls are working fine. If anyone know what's going on, please advise. Thanks, - @NeluLazar
