Morning (just) ..... I'm hoping that somebody else has had this problem, and can therefore offer some advice. I am trying to complete and file a CT600 via the HMRC website ... I'm on the "Type of Company" page and selected Box 0, when I click next the following message appears: X ERROR: This service is trying to auto-save your progress but is unable to do so because the trust settings are not enabled ..... has anybody come across this before, if you can help me fix this, I would be eternally grateful!!!!!
