Apply correct Permissions to WordPress webroot

wp-permissions

# Go to the WordPress root directory
cd /path/to/wordpress

# Change ownership
find ./ -exec chown www-data:www-data {} \;

# Change folder and files permissions
find ./ -type d -exec chmod 755 {} \;
find ./ -type f -exec chmod 644 {} \;

# Correct permissions to wp-config.php
chgrp www-data ./wp-config.php
chmod 660 ./wp-config.php

# allow wordpress to manage wp-content
find ./wp-content/tmp -exec chgrp www-data {} \;
find ./wp-content/tmp -type d -exec chmod 775 {} \;
find ./wp-content/tmp -type f -exec chmod 664 {} \;

worked for me like a charm, Thanks!!!
