Hi @rodrigoreloaded

You need to create a PHP pool for each site and set the user and group to user1.
This will require a lot more RAM than you’re currently using, since you’re only using one pool.
But it will also make everything more secure, since each user only has access to their files and even PHP is only being executed with access to the user’s files.

What solution did you run?

sudo adduser mysudouser1 www-data (adds your user to www-data user group)
sudo chown -R www-data /var/www/example.com/html/
sudo usermod -a -G www-data mysudouser1
sudo chgrp www-data /var/www/example.com/html/
sudo chmod g+rwxs /var/www/example.com/html/
sudo chmod -R 775 /var/www/example.com/html/
sudo chown -R www-data:www-data /var/www/html (If you have many users, just add all to the www-data-group)
