The following error(s) occurred:

Hi @Brian Salzle,

I recommend opening a ticket with Support to help resolve the issue. We would be glad to help you resolve the issue. It appears that your confluence.cfg.xml is missing the proper Oracle dialect, and a Support Zip would help us help you resolve the issue.
