I have been using the following code for some time now and it's been working until the past week or so.
https://twitter.com/statuses/user_timeline.json?screen_name=mina_asad&count=5&callback=?
I get the following message in return:
({"errors":[{"message":"Sorry, that page does not exist","code":34}]});
Is it because the tweets have increased? What am I missing?
