The tweet cannot be sent because the connection to twitter failed


At apple store it was suggested to me to try and uninstall and then reinstall my twitter app on my iphone 5s, i cannot tweet using my iphones twitter button in safari for any website. have been trying to look up in forums about this issue but it keeps bring me back to discussion 1108 which is a year old. Is there a setting i can change in safari app or twitter to allow safari to send the code to my twitter? Please advise.
