My problem is that the gear in the top bar doesn't show options no matter how many times I click it. Same is the problem with new tweet button on the top bar. The search bar doesn't show suggestions now matter what I type. Also, the text in the left tweet bar remains of grey colour instead of being black(which, of course doesn't post my tweet whenever I press Enter). My tweeter is like this since past 3 days. I don't really know what causing it to be like this - all other websites are working fine! Please help!
Did you try restarting your browser? What about using a different browser? How is that related to the problem?
Yep, I restarted my browser many times. But anyway, I opened my twitter account on a different computer(on which it worked fine) and now it's working fine on my previous pc too.
