Can’t get image editor to work in WordPress Media, only shows this error message “Could not load the preview image. Please reload the page and try again.”
I went to see if I have both gd & imagick installed and enabled
Running both these commands I can see that they are enabled and installed
php -i | grep -i gd
php -i | grep -i magick
and reloading using
sudo service ph7.0-fpm restart
it still doesn’t work. Also enabled debugging/debug log in wp-config.php to see if anything shows up but nothing in the error log.

Have you checked user permissions on your files and directories? By default, PHP-FPM runs as the www-data user, so all files and directories would need to be owned by that user in order for PHP to be able to read/write.
You can cd to your root directory (where ./wp-config.php is) and run:
ls -al
… and that should give you the user and group that owns the files. If it’s root or another user, you can run:
chown -R www-data:www-data /path/to/root
… and that’ll change permissions to www-data, thus allowing PHP to read and write to files.
From what I can tell, you need to dig into your PHP error logs (might show up in Nginx error logs). This is usually caused by a WP plugin (or theme) that has a space after the code, which results in a “header already sent” error from PHP. Try disabling all your plugins and changing theme to default 2017 and see if that helps. If yes, then active one-by-one.
