Containers, wrappers missing after latest WP Update (please help, client's website is not rendering)

Hi,

My client’s site, nops.io, has all of the containers and wrappers missing after the latest WordPress update yesterday. We updated BeaverBuilder plugin and the CSS styles are thee, but because of missing layout/wrappers, none of the styles are getting applied and all the content is just loading in basic HTML tags.

Does anyone know why this would be happening and could advise? This is top priority for me and I need to resolve it asap as the site appears to be rendering without any formatting.

Thank you,
