Hi @lindsay.ware, thanks for the post, it looks like there is some malformed custom code being used in an iframe that may be related to the custom chat code:
I would as a first step, remove the custom chat custom code, then republish to see if the issue persists.
It definitely looks like custom code though, there is a problem in the code and the page rendering breaks on the published site.
Recently we announced some changes regarding custom code, so one thing to check is that custom code tags are closed properly, see more here: We’re going hands-off on custom code, it may be good to check if there are any unclosed tags in the custom code.
