wrong themes/ folder permission

[samovar]

The PrestaShop Installer program instructs to set the folder write permissions as I have show below (these are all copied directly from the Installer screens); however, it does not say to set write permission on the folder themes/ or the folder prestashop/.

 

If you do not set write permission on themes/; then, the Theme Installer program cannot copy a new theme-folder into the themes/ folder.

 

The installer says to "Set write permissions on folders and subfolders/recursively", which I do using the command "chown -R", where -R means recursively.

 

[Note: Instead of doing "chmod 755", I'm doing "chown -R www-data:www-data directory_name". This has the same effect. This command is giving ownership of directory_name/ to the Apache web server. So, Apache ends up having write permission on directory_name because it has ownership of directory_name.]

 

What this does in the case of the command:

 

sudo chown -R www-data:www-data themes/prestashop/lang/

 

is to set write permission on the last directory and everything below it.

So; the directory lang/, and every file and folder below it has write permission set.

 

However, the two directories in front of /lang do not have write permission set. So, themes/ and prestashop/ do not have write permission set.

 

Now; here is the really damaging problem: after I run my chown commands to set the permissions the way I think I have been told to set them, and I then press the refresh button on the browser, the Installer Program changes the web page to tell me I've got the permsissons set correctly; it does this by changing the directories from the something-is-wrong red color to the everything-is-ok green color.

 

I am allowed by the installer to move on to the next step of the install with the permissions set incorrectly; but, I think they are correct, because I have feedback telling me everything is OK.
