Hello fellow concretians - I am having a problem and not sure if it is from my own ignorance, so I am reaching out to the forum.

I have a page with a header and nothing else. It is a home page layout. I go to add a block on that page>use the content editor>and within the editor use html. I paste the html content there. I update it and it appears in the editor box as expected. I update there as well. It appears in to the page as I want it to. I publish the edits and the page is perfect. I now go to another page and then return back to that page. This time the content is gone and all I have is the icon (little red x).

Now when I go back to that page and edit it, all content re-appears. Update it and publish the edits. It looks perfect again. But if I leave the page and return, I come back to the red x

Please help111 Any ideas????

Thanks
