Subdirectory dashboards not working

Here’s what I’ve done:

1. Installed WP into a subdomain http://www.mydomain.com/0000
2. Trying to host multiple sites on /0000/v1 and 0000/v2.
3. Installed multi site and have complete access to my Network Admin panel using these instructions: http://codex.ww.wp.xz.cn/Create_A_Network#.htaccess_and_Mod_Rewrite
4. When I click on an individual sites dashboard, I get a “Internal Service Error” message. The only individual site whose dashboard works is the default one in /0000

Here’s what is in my htaccess:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) 0000/$2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ 0000/$2 [L]
RewriteRule . index.php [L]
</IfModule>

# END WordPress

# BEGIN wtwp_cache
# END wtwp_cache

# BEGIN wtwp_security
# END wtwp_security

I think I’ve gone through every source to troubleshoot this.

Something that stood out that may be an underlying issue is the reference to different directories of where WP thinks my htaccess and wp-config live in my Network Setup page.

It says change the wp-config located in:
/home/content/02/11016802/html/0000/

And the htaccess it says is located in:
/home/content/02/11016802/html/

So I’m not sure why the htaccess is not references in /0000/ because that is indeed where it is.

Please help! Thanks in advance.
