Thanks,
Do you have any idea why it wasn't working?

10001
That error response is still valid JSON, so it should cause any errors on the tiggzi side of things

that's the wrong page, sorry, my initial link was wrong, i've fixed it now, the page causing the error is of the same name without _test

didn't fix the problem, fixed the link to the problem, this error is caused by some unfinished code on a testing page.
Try clicking test - device profile now and see if you get the same error

didn't fix the problem, fixed the link to the page that causes the problem

Not sure how that would be related to the issue, and firebug isn't picking it up (though I am getting the same message as you in chrome).
Have you seen that error before?

edit: oops, link was wrong, just fixed

test the page and click device profile

Shared the project with you.

The service is fine, the JSON is valid, and even when the page is told to do nothing with the data it has the same reaction.

Link was fixed, it's live now at http://tiggzi.com/api/
