I am not able to favorite, retweet or reply to any of my mentions, or any tweets on my timeline. I am also not able to search anything on Twitter. I usually go on Twitter in my iPhone or laptop, but now I have attempted on numerous occasions to use Twitter on a computer, and it is refusing to work. I find this very frustrating and hard to deal with. I would highly appreciate it if I could get any help with this problem as soon as possible. Thank you.
