Gosh, I do apologise, that was indeed bumping. However, that comment of mine that you paste above resulted from the fact that my thread had completely disappeared from the forum list. With no explanation or (as I recall) cause).
Thanks for clarifying though Andrew, it does help to know.
I still have had no joy with updating to 3.8.1. Having tried everything I am inclined to start from scratch entirely: delete database, remote site etc and pretend I am where I was last summer when I did all the setting up. Shame. I only wanted to update so I could work on content, but having spent 16 hours this week on trying to update, it'll be quicker to call it a day and start again. Good for the grey cells though I guess.
