title: Why are all my pages, posts, custom fields gone, even though the count is still there?
body: <p>I am building a custom theme in WordPress 5.3. I updated my local database with my staging database but now all of my pages, posts, custom fields, etc are gone. The count says they are there and when I switch to the theme TwentyTwenty, they all appear again. This is what I am seeing. If I change the name of my theme folder, everything works correctly, but as soon as I change it back to what it was called, it doesn't work again.
