I'm trying to edit a wordpress .php file through Filezilla. I've connected correctly to the AWS instance with an ubuntu username. The problem is, I can view and make changes to the .php file but when I try to save those changes or re-upload them I get a permission denied error. I can add the file to the /ubuntu folder but no the /home folder where the wordpress files are located. That's as far as I can get at the moment, I know the permissions have to be changed, but i'm not sure how. Just trying to help out a non-computer savvy friend. Any help will be appreciated, cheers.
Right click on file and go to file permissions and give the permission for file 644 for folder 755
To change file permission on ubuntu use sudo chmod {options} filename link
Make sure that while creating any file or editing the file use sudo vi filename
