The file permissions for core WordPress files and directories are managed for you. They cannot be changed.
As your site’s wp-content folder is the only folder that has files consistently being modified, the contents of wp-content may need file permission changes, especially if you have moved files/folders to Pressable from a previous host.
Directories should have permission of 755, or rwxr-xr-x. Files should have permission of 644, or rw-r--r--. You can update these by accessing files via SFTP.
If you feel that you are having file permission issues, please contact Customer Success.
