    Hello Van,

    how are you doing today?

    Sorry to hear that you’re having an issue with Hummingbird CDN.

    I checked your admin panel and plugins list.

    I can see that you have installed WooCommerce Worldpay Gateway – Worldpay Online Payments for Worldpay to work.

    I think that you downloaded this plugin from this link :

    You can see that the plugin was last updated 2 years back on the above GitHub link.

    It is not recommended to use older plugins especially when there are payments involved.

    I can see that your site is currently live and there are many orders also.

    To further look into the issue can you create a staging environment, meaning a complete and exact copy of this installation into another location/folder in the same server, using a separate database, and perform the test in there instead without worrying about the live site.
