Site root no longer resolves after s2 install

So the site resolved both with and without the www until s2 pro installation. Looked at both .htaccess files and cannot quite tell if there’s an issue. The root htaccess looks fine:

AddHandler php-stable .php

BEGIN s2Member GZIP exclusions

RewriteEngine On
RewriteBase /
RewriteCond %{QUERY_STRING} (^|?|&)s2member_file_download=.+ [OR]
RewriteCond %{QUERY_STRING} (^|?|&)no-gzip=1
RewriteRule .* – [E=no-gzip:1]

END s2Member GZIP exclusions

BEGIN WordPress

RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

And the in-folder version looks like what I’ve seen in other threads. There are no caching plugins and all others have been vetted to work prior to s2. (TablePress, Constant Contact, Contact Form 7, Media File Manager, Disable Comments, Slickr Flickr, UpDraft, Event List)

Site general settings show http://www.ngfa.org as they always have, but it will not resolve at ngfa.org any longer. Both host and domain controller have suggested s2 is the problem. Our first go with it so not experts yet and could use some advice.

Also issues with the login widget and even setting saves have had problems since install. Great system, just a little trouble making it work for us.
