Yes, me too!
That's why lately I access the site by searching on Google, then click on the first result. This way it says the connection is secure.
(Ehh I just noticed it now, but it seems when I type into the toolbar to search for Tapas, it has memorised "tapastic.com" instead of "tapas.io" and that's why it's been like this for me for days, I guess... So this might be the problem in your case, too...?)
