Yes, it did. Thanks. I was on vacation last week. Now that I see how it works, I just need to coach the others who sometimes enter these in the workflow to make them display right.
We are experiencing this same issue on one of our sites.
I had the same sort of thing happen on multiple sites starting last Thursday and repeating over the weekend. Sites would give 503 or 501 error. One one site home page would load from cache (apparently). Back end not accessible. Deleting the rules files (via sftp) would let it load and they would rebuild.
