“Your connection to this site is not fully secure”
That is your browser warning you that although the Epic Gang Website is secure, the images on it might not be. This means you can’t have a secure site with a mirror (iframe) to another site to bypass the security features. On the post Epic Owl’s Second Super Smash Tourney!, there was lots of images that started with http, not https (s means secure). So I fixed that because the images were secure but I told your browser it wasn’t by accident. Any page with a post like that should come up as not fully secure.
