What are the correct Suitecrm 8 folder permissions?

@pgr

www-data

None

@pstevens

udo chown -R www-data:www-data .
sudo chmod -R 755 .
sudo chmod -R 775 cache custom modules themes data upload

So why do I see some posts with things like this

sudo chown -R www-data:www-data .
sudo chmod -R 755 .
sudo chmod -R 775 cache custom modules themes data upload
