Nope, not just you.  I've been seeing it occasionally/sporadically for about the last month or so.  Weird thing is I can just close the browser and click on my direct shortcut again and it's not a problem.

Yeah, have seen that to occasionally.  But as Dave says, just a refresh and same link working just fine.

No, not just you....Kaspersky had been warning me about 5 times a day for months [site certificate] for all of Stardock's sites...and I typically have 4 open [the Admin ones appear OK].  I finally got around to excluding them from Kaspersky's watch as I know they are fine...

I get the https warning on forums from Chrome as unsafe...every time I navigate to them. 

I get it occasionally using Firefox. Twice a day maybe, but I spend a lot of time here every day.

I have not had any issues. I use Firefox for my browser.

Me too and no problems.

Firefox gives me problem free navigation here, as well.
