Hi,
I hope this is the right place to contribute bug reports.
We are using 3.5.1a
on clicking the accept check box for upcoming activities I got the following:
Error calling json server. Message: Not well formed

ReferenceError - Can't find variable: JSON

Response from server:

{"id":1,"result":{"status":"success","record":"4d5 77bb6-ebd5-b373-7e62-439d7a2bdd05","accept_status":"accept"}}

I realise that we a few versions behind the latest.
If I wish to upgrade will this solve the porblem? Is the upgrade process a technical proceedure or like upgrading word or other end user applications?

Many thanks for any guidance.
Best,
Nick
