htaccess redirect problem – "there doesn't seem to a wp-config.php file"

Recently added an add-on domain. Have the following in my htaccess file:

RewriteEngine on
RewriteCond %{REQUEST_URI} !^/wp-admin/*
RewriteCond %{REQUEST_URI} !^/wp-login.php
RewriteRule ^/harmonicfundservices/(.*)$ http://www.harmonicfundservices.com/$1 [L,R=301]
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress

Everything works fine except for redirects from old page URLs below the old subfolder domain (e.g. /harmonicfundservices/about-us or /harmonicfundservices/contact). These generate a browser message: “there doesn’t seem to a wp-config.php file”

How do I edit my htaccess file to fix it so that anything any subfolder (except wp-admin and wp-login.php) redirects to my new add on domain?

Thanks in advance. Mike
