Can't install wordpress on subdomain

Hi, I am moving a website to a new server but I am having trouble moving the subdomain.
I have set the parent site to have unlimited space but when I try to install wp from script i get this error

Failed to install script : This script requires 128 MiB of free disk quota, but only -395.64 MiB is available.

There is this much disk 38.99 GiB used / 58.89 GiB free / 97.89 GiB total.

I uploaded WP an tried the install manually and I get a server error:

Hello,

Sorry about that. There was a bug which we already fixed in our development environment.
