I’ve recently received this message from Envato :
Your live previews (or demos) and item pages cannot contain links that seek to drive traffic/visitors to any external, competing site or service (including your own website if your item or similar items can be purchased or downloaded there).
I don’t think that I have any external link to other places that I know of so how do I find out what they’re on about since I cannot reply mail to ask where this offending link as they’ve stated.
