jeffr0 do you happen to use 1and1 for your hosting?
I have the same problem as you, where no matter what I do, I can’t get the redirect to the SuperCache files to work.
I’ve narrowed it down to this line in the htaccess file:
RewriteRule ^(.*) /wp-content/cache/supercache/%{HTTP_HOST}/$1index.html [L]
(line break added by this post)
And it doesn’t seem to be working correctly with my host.
