I'm trying to relax the upload limits on my site.

I've created a blank server.txt file in the 0_site/settings folder. It's not clear from the docs what value the upload_max setting is expecting; I've assumed bytes.

Therefore the only entry in my server.txt file is upload_max:1000000000.

I've saved the config file, stopped and started the site, but when I attempt to upload any file I receive the warning
At a guess I've got the format of my config setting value wrong. Can anyone confirm how it's meant to be formatted? I don't mind updating the docs once I know.

Thanks.
