Unable to tweet & reply tweets


I’m unable to tweet & also reply my tweets. I use Twitter on both my iPhone & Macbook & I’ve that issue for both. Every time I try to send a tweet or reply, it says ‘Your account may not be allowed to perform this action. Please refresh the page and try again.’ And when I try to retweet or favourite, it says ‘This request looks like it might be automated. To protect our users from spam and other malicious activity, we can’t complete this action right now. Please try again later.’ After waiting & trying again, refresh & trying again. IT NEVER WORKS. PLEASE HELP!!

I can still however get notifications.
