404 page links bug
I was looking for a bitbucket blog (eg: bitbucket.org/blog) and found a weird bug in your 404 page. If you go to any page that gives you a 404 back the ToS and avantlumiere.com links at the bottom will be the 404'd url that was entered. I don't think there are any security concerns (XSS for example) since I can only control the links but it is a funny bug. I included a screenshot incase I didn't explain it weil enough.
