Hi I just want to state the obvious here.
When you go through Codecanyon and click on people’s Live Preview there are so many 404 error pages most likely coz codecanyon is just connecting them up using iframe’s.
Why can’t codecanyon contact the seller’s and tell them they are linking to 404 dead link pages. If the seller does not fix the missing page then remove the seller.
All codecanyon has done is linked to a ton of 404 error pages. Not very useful to many people.
