Foursquare app图标上传问题

Question

在Foursquare上尝试更改App图标时，我在Chorme控制台中收到此消息：

POST https://foursquare.com/__uploadappicon 400 (Bad Request)

Uncaught SecurityError: Failed to read the 'contentDocument' property from 'HTMLIFrameElement': Blocked a frame with origin "https://foursquare.com" from accessing a frame with origin "https://foursquare.com". The frame requesting access set "document.domain" to "foursquare.com", but the frame being accessed did not. Both must set "document.domain" to the same value to allow access.

这里的截图：

有人为此得到了解决方案吗？我已经转向@ 4sqSupport了。
