Okay now for anybody that ever has a problem with a website's certification being expired, all you have to do is manually change your date in your OS (that is if you're on PC), that's what I've been for weeks. I've also found out that if you use the web browser on PS4 it gives you the option to just bypass the warning; yes I was so desperate to be up to date on guro that used my PS4 to access this site.

And on another note for if the certificate ever expires again, once you're on this site you can switch back your OS's date to the actual date it will keep you on the page, just don't refresh the page if you actually want to stay on it.
