If I properly understand the domain name www.windflowergrove.com opens "public_html/myaccount/windflowergrove/" (which I presume is myaccount/public_html/windflowergrove/ but that is not relevant). In this case the options you have set should be:

// NOTE: be sure to leave the trailing '/' at the end of these lines if you make changes!
// * DIR_WS_* = Webserver directories (virtual/URL)
// these paths are relative to top of your webspace ... (ie: under the public_html or httpdocs folder)
define('DIR_WS_ADMIN', '/admin/');
define('DIR_WS_CATALOG', '/');
define('DIR_WS_HTTPS_ADMIN', '/admin/');
define('DIR_WS_HTTPS_CATALOG', '/');

Otherwise with the ones you have set the application will try to use the following URL:

http://www.windflowergrove.com/windflowergrove/


Also the full path to the web site files does not seem to be correct. It should be (I am improvising here as I don't know the exact setup on your hosting server):

define('DIR_FS_ADMIN', '/home/user/public_html/windflowergrove/admin/');
define('DIR_FS_CATALOG', '/home/user/public_html/windflowergrove/');
