I'm having problems with file permissions. I recently upgraded my server and am still having the same issue. What happens is that to have the blog pages viewable I must set the permissions .htaccess and index.php, wp-config.php, etc. in the blog directory to '777'! I know this is not safe, but when I change .htaccess to '750' I get a "Forbidden" message when accessing the index.php and when .htaccess is '777' and all other files are '750', I just get a blank screen when accessing the site. I think many of these files should have permissions set at '640' - does anyone know what is going on?
