I checked the error log on my server and found this one:
[Fri Aug 02 17:33:42 2013] [error] [client 188.8.131.52] File does not exist: /var/www/vhosts/course.dmv-driversed.com/httpdocs/lss8wqreph7490dp4zx8f/LS04Bd25KsJv61/undefined, referer: https://course.dmv-driversed.com/lss8wqreph7490dp4zx8f/LS04Bd25KsJv61/player.html
Can anybody shed some light on why I would receive this message. It appears to be working fine. So, why the message?
Thanks for your help.
