Today, and out of the blue, the localhost Apache server stopped working and left error messages that Port 80 was in use. I rebooted the machine. No cigar. I did check after check with netstat and it was, and is, very clear that Port 80 is not and was not in use.
Since the port was not in use, on a hunch I shutdown WR and bingo Apache on Port 80 worked fine. What confuses is that I did not touch WR prior to these messages. They just started happening and I've no idea how to get this to stop.
