@hellboy9211 You forgot to put the .htaccess file in the zip.
Thank you @sonn1220 for the .htaccess file. The application is working but the total number of files is much bigger than a WordPress installation with add-on. If I could find a similar add-on for WordPress, would be much more lighter for my number of files limitation in my shared hosting.
I have tested it locally. This plugin is best for medical or law or consultancy services whereas mine is a website development business and I don't put any professional because mine is not an agency. So...study this plugin, it has many features, and you can put several professionals
