Hi. I installed the Really Simple Twitter feed on a client's website about a month ago and as far as I know it has been working fine up to now. However if I visit the site as a casual visitor it is now showing yesterday's tweets (apparently posted 1 minute ago). If I log in to the control panel and then visit the site it shows the current tweets. As soon as I log out again it reverts to yesterday's tweets. I have tried deleting the browser cache but this has no effect. Any ideas? Thanks!
