So I’m normally quite good at figuring stuff when I have a problem but cannot get my head around this one so therefore asking for you guys for help.
In my blog section, everything display in the designer and when previewing all looks ok. However, once the site is published and I visit the live URL of the blog article, the header, footer, and other elements are missing.
Thanks, @Brando. That was the issue. All working now. I didn’t even think to check there as the video was playing normally so didn’t imagine the issue would come from the iframe code.
