[solved] Custom sender email address for newsletter

Can’t manage to change the custom sender email address, when I click save, I get a pinning wheel and then a retry CTA, which when clicked does not lead anywhere.

See screenshot.

I have not been able to debug at all.

Here are the errors on the browser

Any pointers welcome :)

For some reason, the save button finally worked after I fixed transactional emails. So, do that first before tacking bulk email and you should be fine.
