Hey there,
Thank you for your review and for bringing your concerns to our attention!
Unfortunately, it is not currently possible to guarantee compatibility between one plugin and all other plugins that you can find on WordPress, as each one of these plugins is developed by different developers.
The request to set up a connection between WooCommerce and Printful can be blocked by other plugins, most often it’s a firewall or a security plugin that blocks access to your site, so we’d suggest disabling those, when you set up the connection.
To best address the specific issue you’re encountering, please reach out to our support team at [email protected]!
