Multisite – cannot access dashboard of one subsite

I thought I had everything working ok finally and then I started getting errors when trying to access one of the subsite dashboards. This happens to be the only one of the subsites that is using domain mapping – not sure if it is related to the problem or not.

I can get to the dashboard of all of the sites on the install but one. That one was working ok. I noticed it was no longer working when I tried to change the theme. I got an error that the page is not redirecting properly. The things that I had changed/updated from the time it was working was enabling the domain mapping option in WP-Super-Cache (it has since been turned off again) and uploaded two themes through the network dashbaord.

This is a subdomain install @ hostgator on WP 3.5. Here is what is the .htaccess file. Any ideas are appreciated.


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

# add a trailing slash to /wp-admin
RewriteRule ^wp-admin$ wp-admin/ [R=301,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^(wp-(content|admin|includes).*) $1 [L]
RewriteRule ^(.*\.php)$ $1 [L]
RewriteRule . index.php [L]
</IfModule>
