WP-Server-settings: contents in wp-content not writeable

Question

When we setup WordPress - we should give the Server the needs the write access to the files. So we should go like so; the access rights may need to be loose.

chown www-data:www-data  -R * # Let Apache be owner
find . -type d -exec chmod 755 {} \;  # Change directory permissions rwxr-xr-x
find . -type f -exec chmod 644 {} \;  # Change file permissions rw-r--r--

After the setup of course we should tighten the access rights, according to Hardening WordPress all files except for wp-content should be writable by your user account only. wp-content must be writable by www-data too.

chown <username>:<username>  -R * # Let your useraccount be owner
chown www-data:www-data wp-content # Let apache be owner of wp-content

Hmmm - here on contents in wp-content we are sometimes doing changes - so we do the final chown later on.

In this case we could temporarily change to the user to www-data with su, give wp-content group write access 775 and join the group www-data or give our user the access rights to the folder using ACLs.

I am facing a problem - with the upload of a demo content - of a theme. It is not possible to do the upload. Can this issue be caused due to the server permissions and the user of the files!?
