I can't add staff to Ghost 🤷🏽‍♂️

Hi @DavidDarnes , Thank you for responding,

I did as you said and got back the same error, “Request was rejected due to server error”

I believe I am facing multiple issues related to emails (with Ghost),
The second one is regarding subscriptions not working, it’s highlighted here.

What steps can I take to troubleshoot this?

Best,
