422 when signing in
There's a relatively high occurrence of 422 errors with POST
requests to the SessionsController#create
action over the past few days, notably post-migration. These all have the same error:
ActionController::InvalidAuthenticityToken: ActionController::InvalidAuthenticityToken
Strangely, clearing cookies/cache doesn't work, and most seem to be Firefox users who have success after trying Chrome. We've been having a hard time pinning this one down.
