How do I fix permissions if they get messed up? Print

Through SSH (if you have access to VPS/Dedicated):

chown -R webX:clientY /var/www/clients/clientY/webX/web
find /var/www/clients/clientY/webX/web -type d -exec chmod 755 {} \;
find /var/www/clients/clientY/webX/web -type f -exec chmod 644 {} \;

(For shared hosting, this is run by the administrator.)
