YAY!!!
I ran the install without creating tables, cleared the cache, and everything is working now.
Thank you so much, Alby, for your patience!!! And thanks Ted & Mark for your help, too.
Here are the correct settings:
#-------------
#Path Settings
#-------------
#Document root as seen from the webserver. No slash at the end
#If page is requested with https use https as root url
#e.g.
http://blah.com
$config['root_url'] = '
http://www.winyahrivers.org';
if(isset($_SERVER['HTTPS']) && $_SERVER['HTTPS']=='on')
{
$config['root_url'] = str_replace('http','https',$config['root_url']);
}
#Path to document root. This should be the directory this file is in.
#e.g. /var/www/localhost
$config['root_path'] = '/home/content/w/r/k/wrk/html';
#Name of the admin directory
$config['admin_dir'] = 'admin';
#Where do previews get stored temporarily? It defaults to tmp/cache.
$config['previews_path'] = '/home/content/w/r/k/wrk/html/tmp/cache';
#Where are uploaded files put? This defaults to uploads.
$config['uploads_path'] = '/home/content/w/r/k/wrk/html/uploads';
#Where is the url to this uploads directory?
$config['uploads_url'] = $config['root_url'] . '/uploads';
