We've just added the confluence trial to our Jira on demand account, and when we click Wiki we get the following errors:
Your on demand instance doesn't include the Wiki functionality.
I've given application access to everyone. I've also tried going to Administation > Wiki and still get the same error.
I've also noticed that "sysadmin" (noreply@atlassian.com) is the only user with the groups confluence-administrators and system-administrators.
