Beaver Builder Selected as Editor Doesn't Even Start

Beaver Builder

I built my entire site with Beaver Builder. Now, even when selected, Beaver Builder won’t start so that the page can be edited. It also won’t start for a new page. My original page (the one that should be there) does appear when I select Beaver Builder–I just can’t edit it.
