Figured I'd just post to an existing thread. I don't have suPHP problems yet because I'm just getting ready to enable this. Thought I'd ask here for any particular issues I might experience. As this is for a VPS (a dozen or so domains) I want to try to minimise downtime.

Currently on all sites, folders are 755, files 664, configure files are 644. The exception is an image cache directory for an addon that insists to be 777. I assume this will run ok as 755 once suPHP is enabled.

I am thinking the first task will be changing ownership, which i'll do through using chown -R for /home/domainname/public_html/. Should I go deeper and chown from /home/domainname/ for every domain on the VPS?

Before taking the plunge, any advice would be welcome. Thanks.
