Looks like just about the same message I used to get many years ago, when I was still bothering to (politely) report problems. After a while, I used to preface my trouble reports with a sentence like "Don't tell me to clear the cache and delete cookies. I know what I am doing and this issue is your problem, not mine."
Too bad Ancestry is still annoying customers (who are probably already annoyed because the site doesn't work properly) by using such an insulting and poorly written message. One of those poorly written sentences isn't even a sentence!
Talk about pouring lemon juice on a paper cut!
