For about a week I couldn't access the site with any browser, I kept getting a message that there was a security issue. Did we have a recent update? Things seem okay now...

I've been on every day this week without issue. Not sure what to tell you.

I couldn't get on either until yesterday.

Super weird. Did either of you clear cookies or use Incognito Mode or your browser's equivalent and still fail to connect? I'm asking because I can't tell if this was a browser issue, a network issue, or something more exotic.
