Site preview / design blank

Anyone who may be able to assist?

I see there are a few forum posts on site preview / design shows up blank all the time … but the solution in those posts seems to be if you are self-hosting.

All I have done is create a custom domain, and set at root - all is working - except the design / site preview is always blank.

If I am meant to change some file in Ghost, I do not know how as I am not self-hosting.

Any advice would be appreciated.

Who are you hosting with?

Do you use Cloudflare to manage DNS?

Thanks - neither. It was, in fact, the Safari browser on my Mac. It isn’t an issue with Chrome. Strange ?
