Just got this email from support.
Thank you for contacting us today. We are currently receiving reports such as yours from users who are trying to use the "create similar" listing function, and are not able to. This is known problem to Auctiva which is related to the new upgrade version of Auctiva which was released a couple days ago. Auctiva engineers are working on a solution to this problem and the fix is expected to be released at any time. We are sorry for the inconvenience this has caused.
