Microblogging website Twitter is warning its millions of users
not to change their login details as it investigates a potential
problem.
Some users have been locked out after trying to reset passwords
or change other details.
"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,"
said Twitter.
