Hi there,
Thanks for reaching out to us.
The current version of the pro plugin is 2.0.17
Please download the latest version plugin from your account – https://getwooplugins.com/my-account/downloads/
After that, try to upload, install, activate and see if the error is gone or not.
Thank you.
Critical Error

We are receiving critical errors on our product pages when the Variation Swatches for WooCommerce Pro is active. We’re on version 2.0.0. If we deactivate the plugin then the product pages load just fine.
