You can just bypass it (in chrome) by clicking advanced and clicking the "Proceed... (unsafe)" link. That's a pain in the butt because you have to do it everytime unless you do other more permanent things such as changing the setting for the site to allow insecure content (which by default is blocked). As I'm typing this the wiki seems to have gone down altogether so they're probably updating the certs.
