WAIT: Adding header or Footer breaks the builder

I have successfully build my header with Mega menu and a footer. As soon as I add them in conditions - entire site, only the header appears and it makes the page content disappear. Not just disappear, but not even load into the page. I have done all the check, PHP, memory, made new header and footer. I have swapped the Header to off, then the footer to off, still breaks no matter what the scenario.

When i trun the templates off, everything shows again.**

OS: macOS / Windows / Linux / etc.

Hi Mick,
Thanks so much for your report!

Please double-check if your header template is “type: header,” and your footer template is “type: footer”.

Best regards,

Ok, I’ll give it a shot, thanks mate. I’ll report back
