Joomla! Forum - community, help and support

I am having a problem with the login. This occurs with either cb login or Joomla login. The live site in configuration.php was configured for http://sitename.org  If a user logged in via http://www.sitename.org the login was not successfull the first time but had to be repeated.  Logging in via http://sitename.org had no problems. I changed the live site setting in configuration.php to http://www.sitename.org and the login works normally however a login for http://sitename.org produces the error now. I am happy that http://www.sitename.org is logging in ok but I am concerned that this may be a bug?
