Comment:

 Four years later I ran into this problem myself, and I had never heard of
 WP_DEFAULT_THEME . This constant isn't mentioned on the Create A Network
 Codex wiki page. This support forum thread eventually led me to the
 solution, i.e. to go into the sub site and (re)select the present theme:
 https://wordpress.org/support/topic/multi-site-subdomain-site-displays-
 blank-page?replies=8

 I believe that this is still a bug, in that it is unexpected behaviour
 that your sub site will simply crash if you are not able to guess that if
 you remove the default theme, you need to set WP_DEFAULT_THEME. I believe
 that WordPress should at least display a sensible error like "Cannot load
 default theme. Please specify one or select one in the Appearance
 section".
