Webserver File Permissions
I often forget what the best permission masks are for web data.
From what I have found out, the standard permissions should go along the lines of
Directories 755
PHP 600
Everything Else 644
Also make sure that all files and folder are owned by the correct users/group.
find . -exec chown www-data:www-data {} \;
find . -type d -exec chmod 755 {} \;
find . -iname \*.php -exec chmod 600 {} \;
find . -type f -exec chmod 644 {} \;
Yeah I know you should use xargs, due to performance but there are not huge number of files evolved here.
