Hi @AllanG, I have been able to reproduce the issue on the site, it appears that one custom code html embed seems to be causing the issue:
Once the custom code is removed and the site published, the issue should resolve immediately.
I would either remove that custom code, or check it, it seems you are trying to embed a custom video. I might suggest an alternate method: [Tutorial] Responsive Video using HTML Embed.
I hope this helps!
