I tried with Chrome and firefox, booth are up to date.
This is what I found from a quick google:http://www.devcurry.com/2010/12/resolve-json-is-undefined-error-in.htm and it seems to suggest upgrading your browser as a fix. OR if you are using MWIE, getting FireFox (what the forum was catered for) or Chrome browsers.
"...JSON error..." Have you reported a bug?
