Too many redirects after Editor made changes?

Hi all,
Re: https://denhardtproductions.com/

My client just made some text changes via the editor and reported that they are no longer able to pull up their website. I can confirm that it isn’t working.

I’m seeing “too many redirects” on three different computers in both Chrome and Safari. I found a forum post ("This page isn't working" ERR_TOO_MANY_REDIRECTS) about this that suggested browser cache which I did but it still isn’t working. And, I suspect that three different computers wouldn’t all have a browser cache issue at the same time.

This was working and I’ve made no DNS changes since then.
Any ideas?

Thanks!
Jen
