Error cloning with 4.4.2 – Test Blog Name 1000000

The internal test blog name is ‘1000000’ which isn’t supported in the latest wordpress build. It requires letters too (that’s actually the error that wordpress complains about “Sorry, site names must have letters too!”)

File ns-wp-utils.php, line 13. change the test blog name from ‘1000000’ to something like ‘nsclonertest’ (which is the blog title without spaces and lowercased)

Yay it works now.
