The first thing is, you need to upload files in ASCII mode, not binary mode. Binary is for files such as images, zip files, executables, etc.

ASCII should be used for all text files -- .php, .js, .html, .asp, etc. Anything you can open in notepad and read.

but they mention all the time that you must upload in binary mode and they repeat it many times
