im having a nightmare trying to install c5.
normally it works like a charm, but for some reason even though its on my same hosting, every time i try to install version 5.7 it starts installing then i get this error:

550 Can't change directory to /www/hutch/application/config/doctrine: Permission denied.

I have tried this now several times on different accounts, even made new accounts through cpanel in case the other account was corupt in some way, but the result is always the same.

I know the permissions are correct as have checked this many times before trying again.

Anyone got any ideas please?
