Can't edit the Home Page

I am having difficulty getting the home page to display when I hit edit.
I am using a child theme of ULTRA.
The page I need to edit (and I used to have no issue) is a main page (no parent) but when I click to edit it just does not display anything. All the other pages work fine.
I have tried emptying the cache but that has not worked either.
Would appreciate some help! thank you!
