Hi... I'm a newbie, both to this forum and Android Tablets. Bought a Lenovo tablet for Christmas and we had been fumbling our way around it, slowly figuring things out, but for the last week or so, any internet use, especially facebook, has been made impossible by a persistent "Security warning: There are problems with the security certificate for this site" window. It offers 3 options below: "Continue", View Certificate", or "Go Back". The only option that actually functions is "View Certificate", which doesn't get us very far. So we are effectivly blocked from facebook, and most other internet sites we try. This never happened until a week or so back. Any idea how to remedy this? -Bmack
