There are some commandments that are ignored. One is honor of one's parents. Though there are plenty of cases where reason dictates that one's parents are not worthy of honor or respect because they are crazy, still there are lots of cases in which one's parents are good people and still the commandment is ignored.
Living in Israel is another one. The Ramban' (Nachmanides) counts it as one of the 613.
The Rambam (Maimonides) does not count it, but it might still be a branch of the command to conquer the Land of Canaan.
Bitul Torah [not learning Torah when one is able] is certainly one of the most wide spread problems.
But one that I would like to include is Physics and Metaphysics as brought by Maimonides. Somehow that opinion of the Rambam is ignored even thought it is more or less repeated by many other Rishonim.
I also have an ambition to start a place to learn Torah on the name of the Gra and Rav Shach for I feel that there is no place where one can learn Torah nowadays that is not a den of the Sitra Achra [Dark Side] .[Unless there are already places that make it their business to walk specifically in the straight path of the Gra and Rav Shach with no compromise what so ever.] The trouble is that immediately when people want to start walking on the path of Torah, that is when the Sitra Achra gets them. And gets them for keeps.
So there is a lot of things that people do that they think are mitzvot that they actually will have to repent on.
