Probably a dumb question. I installed the latest version (0.5.3). On the configuration page, I get a warning message that my public_html file is writeable and that I should change it to read only.
The permissions for my public_html file (which contains my WP installation) is set to 755. If I change it to 754 or 744, I get a 404 Access Forbidden error when I try to log in to or access the site. Don't I need the owner permissions to be Read, Write, Execute? Why is Super Cache concerned about the public_html file being writeable if it is only writeable by the owner? Should I be concerned about the current settings and, if so, what should they be?
