Any clue that this error was? It’s a new site I just started on my local machine so I don’t have a test site. I created a page and initially added a container and grid and then decided to move the paragraph and image blocks out of the container onto the page and deleted the grid and container blocks. It’s just an image block and a few paragraphs, but when I try to load the page I get the error in the screen shot: https://www.dropbox.com/s/tffbzmrg1jn849s/Screen%20Shot%202020-12-01%20at%204.11.45%20PM.png?dl=1
