Send Button

When I am upgrading a building. I need to request items from neighbours. The items that post to the news feed work fine but items that you must request from a list of neighbours doesn't. I can choose the neighbours but when I press the send button nothing happens. My neighbours do not receive the request.I have tried playing with google chrome and IE. same result. Also when I enter the game my message box does not pop up and if I click on the envelope and go to the message box it its empty. I know people are sending requests and gifts because I chat with them but the box  always says no messages.
