Bulletproof Security Not Working

I installed Bulletproof Security and added the following custom code to the bottom box of the custom code area:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^ashevillecommunityyoga\.com$ [NC]
RewriteRule ^(.*)$ http://www.ashevillecommunityyoga.com/$1 [L,R=301]
RewriteBase /
RewriteRule ^index\.php$ - [L]

Then, I created a default .htaccess file, then a secure .htaccess file. Then, I activated it for the root folder, then I activated it for the wp-admin folder, and when I did that it sent me to the login screen and would not recognize my log credentials, nor did it even give me an error.

Also, the site would not load, saying “this page isn’t redirecting properly”. So, I deleted the root .htaccess file from the server and that, at least, got the site back up. All pages but the homepage were still not loading, until I went int Permalinks and hit “Save Changes” on the custom permalink structure.

I’ve never had this this problem with BPS before.

Another post on this topic said,

Also additional things to check:
Do you have a custom permalink structure?
Are your site settings correct under WordPress Settings > General Settings?
Double check that your WordPress Address and Site Address are correct.

As far as I can tell everything is normal with those, though, yes, we do have a custom permalink structure, which has never been a problem in the past, and the WordPress Address and Site Address both point to http://ashevillecommunityyoga.com.

Help?
