It's easy to forget about an echo or a var_dump() that you may have been using in the past to test how your script is working.

In my own script I had a var_dump(), which I had forgotten about, that wasn't using JSON_encode-ed text and sent plain text to the browser. This broke the dataType:"json" requirement and caused the success function not to work.

Took me a while to find the problem as I had ctrl+f(ed) for echo only and forgot about the vagabond var_dump().

printf is probably another suspect.
