When people tried to access the Town of Bethel's Facebook page last week, they may have received a security warning that the connection was not secure and that private information could be exposed.  First Selectman Matt Knickerbocker says there was no security problem with the site, and no private data of any kind was in danger of being exposed. The problem was that the site's security certificate expired and there was a delay with the renewal.  The cause for the delay is not yet known.  The security certificate has now been reinstalled and the site is functioning normally again.  Town officials apologized for any concern this may have caused in the community.
