I want to use only header and footer of my existing Wordpress website in WHMCS instead of WHMCS`s header and footer. I want to use default WHMCS template also.
How can I do it ?
I was try by creating a new page with [wcp_content] short code. Then I am getting error at # https://www.webhostingpeople.net/demo.html
