Hello, as you can see in the following image, I can not write the root folder of my web directory. How should I call my folder?
I'm working on web hosting with cPanel( php7)
Sounds like you are referring to the FileRun user's "home folder".
To find out the absolute paths of your server's folder, you should contact your server administrator (or hosting service tech support). This person will also be able to help you assign folder permissions so that PHP/FileRun can access them.
