Saurabh Thank for your reply,
For the foodomaa app, I install and run normally in my main site: yourdomain.com
Only one problem that I am facing is how to install the wordpress site in the subdirectory: yourdomain.com/wordpress
(Actually, I installed wordpress site in subdirectory aleady, however, when I access: ""yourdomain.com/wordpress"" then it will be redirected to: "yourdomain.com")
Very thanks for your reply.
