Request:
I'm a new user to Confluence, and pretty new to Atlassian's other products. This might be some standard issue that is a quick fix. Looking through the community, I found some other users that are having this problem, but the reports were several versions ago. If anyone can at least give me some good troubleshooting tips, and what to do next, that would be awesome.
