'I was of the impression that you were aware of a link between the error message 'error/baseelementchildnameconflict', the moodle version being used and how my courses are setup, hence asking the questions you did. Is there such a connection as from reading the bug explanation, it seemed to refer to restoring rather than backing up?'
Sorry if you got the wrong impression ... what I did was attempt to help. Did a google search for 'error/baseelementchildnameconflict moodle' and got the hit for the tracker posting. Read the tracker posting and while it sounded similar it may not have been. It did refer to a course format issue. From previous experience, know if a backup putzes, restore may not work.
I do NOT know ... first hand ... if the tracker item is related to your issue. So let's forget that! Have never seen nor experienced the same error (but then again, don't run Windows).
Since there is no Windows specific forum now, Windows users will post into what forum seems appropriate to them.
Ok, Windows users ... am bumping this to you all! If you run Windows, help Michael!
