Hi @eyeswiseopen, thanks for reaching out. It sounds like there could be a few things in play here. It could be a plugin conflict, or a server setting somewhere that’s causing the images to get blocked. Let’s try these steps in their order to try troubleshoot:
1. Deactivate all plugins except WooCommerce and Mailchimp for WooCommerce, and try again. To learn more, hop over to WooCommerce: Fixing Theme and Plugin Conflicts: https://docs.woocommerce.com/document/how-to-test-for-conflicts/
2. If deactivating another plugin doesn’t solve the problem, enable debug logging on the Mailchimp plugin by going to Logs -> Logging Preferences -> Debug. After that’s done, save a product & please provide us w/ debug log of product update so we can take a look.
We’ll keep an eye out for your reply, look forward to hearing back from you.
Thanks!
