I'm using the AWS/Bitnami/Wordpress stack to install WP multisite (3.5.1-1) with a subdirectory structure.
I can create sub-sites, however trying to view a sub-sites dashboard results in a 'redirect loop'. Additionally, when I view a sub-site it appears that the theme/plugins are broken.
I have installed multisites before with no issues, so am assuming that this is something related to Bitnami itself. I've searched through the database to confirm that all site URLs are the same as I read that that was a common solution, however I'm still facing the same problem.
Here is what's in my .htaccess:
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L]
# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $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).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]
</IfModule>
# END WordPress
