It does appear that some of the documentation for ACF4 is no longer available. There really isn’t anything that I can do about that. The best I can do is to say that if you have a question about ACF4 to post the question here and someone will do there best to help you. If you do that you should include the fact that you’re using ACF4, that will speed things up.
Hopefully, the long awaited release of a free version of ACF 5 will happen eventually.
