Filetype not allowed - zip - 1.8.9

Hi there,
i’m trying to import a layout, exported from my demo system. But it won’t. Filetype not allowed

Is it docker or custom installation?

Could you please go through Report Fault Wizard and share the logs with me? (perhaps over private message).

I’m sorry, I tried another browser now and it’s working.
So if you are on a Mac, don’t use Safari to import layouts.
