List appearing on PC but not Mac

[jshster]

Hi guys, I have my Flexdatalist setup to read a .json file. Basically it's a list of teachers. What we're finding is that when they add a new teacher - which generates a new json file - that they cannot see the new teachers, but I can.

I've checked and re-checked the code. I've modified the reference to the .json file to have a query string appended to the end with the current time to ensure it's the latest version .... and still nothing.

Any idea on how this could be possible? Unfortunately it's in a content management system so I can put a jfiddle online or anything.
