Recently active topics in Twitter tagged with older button disabled

Twitter is no longer showing the "Older" link on the web. I can still get to older tweets by hacking the URL, but why should I have to?

twitter older linking is not working, the button is still there, but cant be clicked. therefore my older entries couldn't be shown...is there a bug or something? or is there any setting adjustment needed to be made? can you solve this problem asap? Thanks.

Why can't I see previous Tweets? I wanted to look back at Tweets I missed during the night and the Older button is missing from the bottom of my Home page. Where did it go and when will it be back?

It seems to have disappeared from the bottom of the page. I'm using Firefox, and I really can't find it. I've refreshed the page several times.

Suddenly all my 'older' posts have disappeared. I just have one page of current tweets from me and the people I'm following, and the 'older' link is inactive. Hope you can fix this soon!

My older button is also disabled. The button is there but is greyed out. It has been this way for more than a week. Really frustrating because I can't read anybody's older tweets for the day. However the older button is not disabled under anybody I follow or my replies and archives.

Okay so I put in the URL to go back myself but I can only go to page two and now my older button is blue again on my first page but on my second page it's grey and disabled still. Help me -- I want to go back and read my older tweeters.

I can't page back in my own archives; the archives of others appear to be unaffected

The "Older" option on my page is greyed out; this is not a sitewide issue as every other user's archives that I've checked has paging enabled.

What have I done wrong, and how can I fix it?
