Sorry for the inconvenience folks but through no fault of our own the forum was down for a wee while today. The SSL certificate (which gives us the HTTPS with green padlock symbol), was not automatically updating and the browsers were "seeing" it as "expired". Forumotion are resetting all affected forums manually with a global patch. Looking at the URL address bar, it seems we are back to normal. I sent an e-mail to all members with a workaround if you are still having problems, so check your registered e-mails please.
