I already had one buyer on my new gig when I got the notice it needs modification. Evidently, they don’t like the image, but I don’t have any other image to use, so I don’t know what to do about that. What I want to know is if I can still complete the gig that was already purchased? The gig is offline, but does it still work for communicating with the buyer?
You should still be able to complete the order as long as it was made before you were told to modify your gig. As far as I know, Fiverr doesn’t interfere with orders themselves unless you or the buyer request it, or what you were offering was against the TOS.
