I wish I could tell you what happened. Strange error came up preventing display of the board yesterday. Recycled the server which didn't seem to help. Was able to get into the administration area of the board and manually closed it. Cleared the cache. As soon as I did that, the board seemed to start working again. Must have been in a strange mode. Performed a complete virus check of the site. Nothing found. Will keep the board up now and see if anything strange occurs.
