Unfortunately we experienced a major problem with the new VLE server on 18th February. This required a restore of a backup image and it is possible that some items have been lost. This should only have affected data uploaded overnight between 22.00 on 17th February 2014 and 09.00 on 18th February 2014 UTC. Data uploaded before 22.00 on 17th February should be unaffected.
If you uploaded anything or logged into the VLE and completed a quiz etc. during this time please try again.
My apologies for any inconvenience this may have caused.
