Restore Virtual Servers does not work anymore

I’m on debian9 and I want to transfert a site to another server with the “Restore Virtual Servers”. It was working last week, using SSH server.
Now it’s stay block on “Show What Will Be Restored”.
I try to restore from locally, same result.
Do I have to downgrade to 1.890 from 1.900?

I check /var/webmin/miniserv.error : nothing at all. I try with Chrome, Firefox -> same results

Ok, it works with command line virtualmin restore-domain .

Hello All and Virtualmin administrators…

I am getting the same problem over here: trying to restore a backup hangs indefinitely on “Show what will be restored”.

Please … help us.

It is a bug, explanations and fix right here :
