Clicking the "I Love Hats"-button on a site in private beta shows the "An error occurred while joining - please try again" message. Dev tools show this response from the server:

 {"ErrorMessage":"failed to opt in to winter bash"}

1 Answer 1


The reason was an inconsistency between the settings: Aviation isn't activated as a hat-receiving site on winterbash2013.stackexchange.com, but our network default setting on the Q&A sites for "should the Winter Bash JavaScript" be included is "yes" (because that's 95 out of 111 sites). The newly created Aviation site inherited the network default and thus included the JavaScript. I've turned it off now; the site should focus on being born, not wearing hats :)

    But... we want our hats! Especially the propeller-type ones!

    So, the Chuck Yeager hat can be earned on every site but Aviation? Oh the irony...
