CheckoutWC requires a few things to run properly.
PHP Version 7.1 or later
CheckoutWC requires PHP version 7.1 or later.
Which version of PHP should I update to?
You should update your PHP version to 7.4 or higher. Ideally, you should upgrade to the latest version your web host offers. Most sites can upgrade to PHP 7+ without issues.
How do I update my site’s PHP version?
Most web hosts can easily update your PHP version. In most cases, you can upgrade within your web hosting control panel or by submitting a support ticket to your host.
WordPress 5.2 or later
You should be running the latest version of WordPress at all times for the best security and performance. However, we do support WordPress 5.2 and later for sites with unique circumstances.
WooCommerce 5.6 or later
While we recommend running the latest version of WooCommerce, CheckoutWC will function correctly with any version 5.6 or later.
