Wp to twitter 403 :forbidden error


my wordpress blogs on publishing were autoposting on twitter but suddenly it has stopped working and showing me the following error

403 Forbidden: The request is understood, but has been refused by Twitter. Possible reasons: too many Tweets, same Tweet submitted twice, Tweet longer than 140 characters.Not an error from WP to Twitter.
P.S Neither of my posts are of 140 chars nor did i submit my post twice or something of that sort.
please helppp!!!


I have the same problem too. Is any solution?
