Hello @LGFproductionsINC,
Thanks for writing in!
I have logged in and check your About page. It seems that it has been edited outside of Cornerstone. Please understand that you are not supposed to switched between editors. pages built with Cornerstone can only be edited in Cornerstone. Any changes made outside of Cornerstone editor will be discarded when you try to edit the page back in Cornerstone. The cornerstone data may have been corrupted which is why it is no longer editable.
if you happen to copy a text codes from other pages or WP installation and inserted to your new page, it will still not work and again will not allow you to edit the page in Cornerstone. All those text codes will just be discarded and you will be given with a blank slate. You may need to create the page from scratch instead.
If you have an existing page built with Cornerstone and would like to use it in another page or WP installation, you can save and download it as a template instead. Please see “Working with Templates” in this article: https://theme.co/apex/forum/t/cornerstone-content-builder-layout/122
Hope this helps.
