Do you see the file called DO NOT UPLOAD FILES HERE in your screenshot? Because you should not upload your files there.
Instead, your files should be uploaded to the htdocs folder. Which you have deleted. So please create a folder with that name and upload your files to it.
there should be a folder labeled “htdocs” in the file manager. thats where you upload your files at. if its not labeled htdocs then it will be labeled as your domain.(i.e example.com)
