I found out that my issue with this was a javascript file conflicting. To be more specific, the file did not exist and was for another plugin. Once I copied the offending file to it’s correct folder, the js error went away, and my uploader fields for Magic Fields came back. This is likely the issue in many cases. Use “Inspect Element” in Chrome or Firebug in Firefox. I imagine that MF uses javascript and can’t load if another js library is jacked up or missing.
