Hello Siegfried, Yes, it is possible. I see at least one cause: you made twice the subscription to this feed with 2 different callback urls ["hub.callback" param when you subscribe] even located on the same site.
Then, on each update, the hub will call you back twice: once on each url. This may for example happen when you change the structure of your callback url in a new version of your app and you do an automatic regular re-subscribe to the feed -> the callback url should be carefully thought at beginning and never changed or subscription should be properly cancelled and resubscribed when callbacl changes. regards didier On Apr 22, 11:15 am, Siegfried Hirsch <[email protected]> wrote: > Hello, > > I have a small app running, which subscribes to feeds on PuSH.
