# fix-wp-permissions.sh — reset file and folder permissions on a WordPress install.
#
# Defaults (WordPress-recommended):
#   directories      755
#   files            644
#   wp-config.php    640  (use --strict for 600)
#   .htaccess        644
#   wp-content/uploads  writable by the web server group (775 dirs / 664 files) with --group-write

#   curl -fsSL https://gist.veru.se/Veruse/fix-wp-permissions | sudo bash -s -- -p /var/www/example.com -o deploy -g www-data --group-write
