When I click on my username, there is the option "Switch to Old Twitter" but when I click on it, this URL opens with the following plain text:

403 Forbidden: The server understood the request, but is refusing to fulfill it.

What's going on? How can I switch to Old Twitter?

I was getting the same error message too.

Clear your cookies and log in again - it should work then. I have provided a screen shot just so you know I am not making it up :)

Old Twitter


After a bit more digging it appears that there is an issue with Twitter. You can switch back to the old twitter but you have to use the link that appears in the blue banner at the top of the page.

enter image description here

If you try to use the option in the drop down called Switch to Old Twitter it won't work.

I think the reason for this is that it executes a HTTP POST with some hidden form values. One of these values is the authenticity_token. This value is not set for the drop down option. However, looking at the link in the banner, the value is set.

I suspect this is what is causing the problem.

By clearing your cookies your are forcing Twitter to display the banner which has the correct hidden form values set. This is what enables you to view the old twitter.


This issue has now been fixed by Twitter and you can simply switch to the old version of Twitter using the drop down menu option.

The above answer is not working I would say. If you are new Twitter, click on the username on the top right. Then click on the Switch to Old Twitter, this again showing the error message given above. – MoG May 3 '11 at 17:04
@Mohan - I have updated my answer with some further details. It outlines how to get this working and the suspected cause of the problem. – codingbadger May 3 '11 at 17:16
