We highly recommend that any website using UpStream also uses PHP 5.6.

You can see our official recommendations at the UpStream page on WordPress.org:

official PHP recommendations for UpStream

Why PHP 5.6? Because PHP itself does not support anything lower than 5.6. Click here for more details on PHP version support. Any version of PHP before 5.6 doesn’t have security updates and will not keep your site safe.

WordPress officially recommends that you use PHP 7.

Does my site meet the PHP requirements?

If you are unsure of what version of PHP your site is using, you can use the Health Check plugin to find out.

  • After installing the Health Check plugin, go to Dashboard, then “Health Check”.

Other recommendations

  • Database: MySQL version 5.6 or greater or MariaDB version 10.0 or greater.
  • Server: We recommend Apache or Nginx as the most robust and secure server for running WordPress, but any server that supports PHP and MySQL will do.
