Well, the error is pretty clear. Whatever your createUser.phpscript returns in www.downloadHandler.text is not valid json. Have you actually tried to debug your issue? Have you tried printing what is returned from your script?

We can’t tell what your PHP script returns since we don’t know what that script does. Maybe it doesn’t run properly and throws an exception and the returned text is just an error message and not the result you’re waiting for.

However serverside scripting is out of scope of UnityAnswers. Apart from that we can’t really answer anything since the important parts (the PHP script and / or the actual returned text) are missing.
