Hi.
I had a buyer who liked my work and request a modification.
and I did in a few hours and I waited for his reply.
this happened in 24 th June.
but today morning I got a notification "the Order Canceled by Fiverr CS"
what happen to it ?
Why These type of buyers still in here 
I sent a PNG file because he liked my 1st design.
I donât know the reason for do it.
Screen shot attached.
Thank you.
Well,
it looks like you did not deliver this order via Deliver Now button. At least it looks different from my usual communication thread.
And if you donât deliver officially, your order will be cancelled.
We canât see the messages from buyer!

So can you share a screen shot where your buyer liked the work?
Thanks.
And that was probably your mistake. Always deliver via that button.
If the client doesnât like it, they will ask for modifications again - they already know how it works 
You might be able to convince Customer Service to activate the Gig again. If not, have the client place another order to make up for the money you lost.
If the client values your work, they will certainly be kind enough to help you out.
It, to me also looks like you didnât re-deliver. Unfortunate outcome.
Reply to @voicetex: I deliverd my work. then he sent me MODIFICATION REQUEST 
Then I didnât Deliver it until he Fully Satisfied.
Hope you understand my System
