Twitter is currently investigating on a problem. And while this is being resolved, Twitter advises everyone not to change their username, email address or password or the bug will lock your account out.
We’re currently researching reports from users who are locked out after trying to reset their passwords or change their email address or user names. This seems to affect new users as well as long term users; we do not advise changing your user name, email address, or password at this time. We will update Status with more news as it becomes available.
