A little shield symbol suddenly appeared in the url of my tab and when I hover over it, it says "This site is trying to load scripts from unauthenticated sources". At the same time, the bookmarks at the side of my age broke; the text on them is horizontal instead of vertical. I have a feeling that these two issues are related, since they started at the same time, but I'm not 100% sure. The shield and the horizontal text both appeared after I visited the Buy CSC page a few minutes back.
Windows 7/latest Google Chrome/Toshiba laptop.
EDIT: Corrected a typo.
Try changing your address bar from https:// to http:// subeta. It doesn't change on its own once you leave the buy CSC page but it causes a lot of problems around the site.
