Hi, I’m having a problem with the Layout builder, the preview isn’t loading. Getting the message Http/https mismatch in builder error. I’ve seen other people have had the same problem and it was being caused by incorrectly set up https.
I’ve checked the server set up for this site and everything looks ok. None of the other previews seem to be causing a problem, e.g. pages/header/footer etc.
Could you please take a look, I’ve run out of ideas.
Thank you
