the page layout has disappeared from my Tabs component - was there, then disappeared. i have restarted and still not there.
I’m not sure what you mean by “page layout has disappeared from tabs.” It helps if we see the context, not just a portion of the Page Layout panel. All I can tell is that you’re working on your Home page, you have a background in which you’ve put a logo and container with a tabs component, and you’re IN the Page Layout panel.
I suspect you want to be in the Pages panel, which is not the panel you’re in.
