Install WP-CLI and check if WP-CRON works

wpcli.txt

1. Download wp-cli.phar using wget or curl:
curl -O https://raw.githubusercontent.com/wp-cli/builds/gh-pages/phar/wp-cli.phar

2. Check if it works:
php wp-cli.phar --info

3. To be able to type just wp, instead of php wp-cli.phar, you need to make the file executable and move it to somewhere in your PATH. For example:

chmod +x wp-cli.phar
sudo mv wp-cli.phar /usr/local/bin/wp

Now try running wp --info.

4. Check if WP Cron works:
wp cron test

If you get "Error: WP-Cron spawn returned HTTP status code: 401 Unauthorized"
Put this in .htaccess:

# Exclude the WP CRON and other scripts from authentication
<FilesMatch "(wp-cron.php|another-script.php)$">
Satisfy Any
Order allow,deny
Allow from all
Deny from none
</FilesMatch>
