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.**
