WordPress permission issues. I’m getting Forbidden You don’t have permission to access this resource even after setting the below permissions. This happens while trying to access pages like wp-admin/plugins.php. The site itself is ok

sudo chown -R www-data:www-data /var/www/site
sudo find /var/www/site/ -type f -exec chmod 640 {} \;
sudo find /var/www/site/ -type d -exec chmod 750 {} \;

After this it was still not working. I decided to give the directory full permissions chmod -R 777 but still it didn't work
