Too many redirects after Editor made changes?

Hi all,

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?
