When I open this page on Elements (WordPress category) - https://elements.envato.com/wordpress
The live demo/preview for first item “SUVAD” does not work.
The live demo/preview for the 4th item “Construction” does not work.
And there is lot more items which does not work or link is wrong.
Personal, I don’t have/sell items on Elements and I am not interested (don’t have a need) to buy there - but all this looks really unprofessional. You must have more control over that - hire someone just to check if are all items live or not.
