Hey @mattw1000,
Thanks so much for reaching out! That does not sound ideal at all and I’ll be happy to take a look and see what’s up. To clarify a bit, the MailChimp for WooCommerce integration is not programmed to make blog posts, and we wouldn’t expect it to cause the behavior described. That being, said something weird definitely seems to be going on here, so I’d love to dig in. Do you mind getting back to us with your WooCommerce System Status Report? That will provide us with your environmental details and allow us to try to replicate the described behavior on our end. Also, could you please provide us with the full 500 error response you’re seeing on your end, as well as what steps were taken leading up to seeing that error? A screenshot of the error would be excellent, if possible. Additionally, have you ever shared the connected MailChimp API key anywhere? If so, that would make it vulnerable and render the connection insecure. If the API key was ever shared, I would advise disabling that key and trying activation with a fresh generated MailChimp API key.
Thanks! I look forward to seeing your reply and helping out as much as I can.
