Hello @dimego
Thank you for reaching out to us, we are here to help.
The 503 error is?an HTTP status code that appears whenever the server is unable to handle a request. I would expect that this error might be caused by a plugin conflict, and this can only be confirmed by performing conflict testing. A full conflict test is done to rule out eventual issues with the theme or a different plugin. We recommend temporarily activating the default theme Storefront and disabling all other plugins except for?WooCommerce and?PayPal Payments to see if the behavior persists.
Here’s a guide that explains the steps in more detail: How to test for conflicts. Please see if our plugin works when all plugins (except WooCommerce and PayPal Payments) are turned off and the theme has been replaced. If that works, you can switch on the other plugins one by one and see when the issue start to occur again.
Let me know if this is possible for you or if you require any assistance from our end.
Kind regards,
Joost
