Help with Permissions Breakdown

[JessieSager]

Hello,

 I am being told by my webhost that my site cannot get the permissions 777 or 775 because I will be hacked. They are requesting I asked for the specific permissions breakdown that I should have.  Currently the issue is I cannot import/export, or update anything within the website as I keep getting this error:

Temporary Directory /home/heartpetsupply/public_html/admin/system/data/ is not writable! Please change permissions to proceed.

Your help is greatly appreciated.

755 means write for file/directory owner and listing(reading) for group and other users.
Your web-server works under some user. Usually it's a username that your account registered. In your case it's a "heartpetsupply".
Looks like somebody uploaded your files with wrong permissions or did it by security reason.
So, you should to set 755 permissions for all directories and files in the list.
You can do this via cPanel FileManager. Just select directory, for example default_usps. Change permissions and files inside.
If you do not plan to use extensions default_usps and default_spanish(language pack), you can just delete them.
