I'm currently using JIRA Core and inviting users from Administration User Management. When the user clicks on on the invitation email, it brings them to the JIRA atlassian space, but with no way to view profile. The page is empty and clicking the log in button brings them to the same blank space.
In addition, the user management list shows them as "invitation pending."
They are all already added as people to a JIRA project, but need to be able to log in to view issues.
