Try this script and change domain and subdomain according to their names and also post wordpress related question to wordpress.stackexchange
RewriteEngine On
# rewrite subdomains to separate folder
RewriteRule ^subdomain/ - [L]
RewriteCond %{HTTP_HOST} !^www\.domain\.com$
RewriteCond %{HTTP_HOST} ^([^.]+)\.domain\.com$
RewriteRule ^(.*)$ subdomain/$1 [L]
# or if you want to rewrite sub.domain.com/test to /subdomain/sub/test
#RewriteRule ^(.*)$ subdomain/%1/$1 [L]
# force www
RewriteCond %{HTTP_HOST} ^domain\.com$
RewriteRule ^(.*)$ http://www.domain.com/$1 [R]
# BEGIN WordPress
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ./index.php [L]
# END WordPress

Did you install Wordpress in the offering-pages directory? If so, you need to change index.php to point to your directory where Wordpress is installed.
From:
require(dirname(__FILE__) . '/wp-blog-header.php');
To:
require(dirname(__FILE__) . '/offering-pages/wp-blog-header.php');

SOLVED!!!
The top site's custom Permalinks (anything other than "Plain") clash with the subdirectory site's custom Permalinks (anything other than "Plain").
Both cannot be set to be custom (without a complicated solution).
To fix (and not get "Invalid JSON response" when modifying or creating Posts and Pages), simply delete the top site's .htaccess file (in the root directory usually under public_html).
And to prevent future clashes, go to the top site's site Settings > Permalinks in WordPress and change the setting to Plain, delete any Category and Tag Base, and click SAVE. When you click SAVE, a new .htaccess file is created or the old one is overwritten for that directory (and Plain actually means an empty .htaccess file or no setting).
This means that you won't be creating pages and posts with pretty URLs from the top site (for that specific site you'll have to use an auto-generated post or page url like example.com/?p=123 instead of example.com/postname).
