Moodle courses not syncing on wordpress

We tried to integrate our Moodle courses with our WordPress site as per instruction given here https://edwiser.org/bridge/documentation/ and https://edwiser.org/bridge/faqs/. But, unfortunately the courses/users aren’t syncing. Here are the potential details that might help to understand our systems.

Moodle site: https://elearning.mhri.com.au
Moodle Version: 3.1.5
PHP Version: 5.6.36
Language: English (en)

WP Site: https://www.wmhi.com.au
WP Version: 4.9.5
PHP Version: 5.6.36
Language: en_AU

It would be great if you please help us integrating Moodle with WP. Please also let us know if we buy the Edwiser Bundle, can we get the RemUI theme free? Is it bundled?
