Suddenly I have a message saying 'Please login to access the p06-caldav.icloud.server CalDAV server' with boxes for Login and Password. I've no idea what this is and I haven't found any credentials that stop it coming back. As icloud appears in the string I opened another tag in my browser and satisfactorily logged into iCloud but my iCloud credentials don't make this dialog go away. I have no record of having set myself up on the p06-caldav.icloud.server CalDAV server and I don't know what it is. There is no password reminder link or whatever on the dialogue. I use Google mail and calendar and I have an iPhone. I don't know if this is relevant.
I would be grateful for any suggestions.
Thank you.
