Hello.


We are migrating from Confluence 6.6.0 to 6.6.12 When booting version 6.6.12 we are getting this error.

--------------------------------------------

Populating setup configuration if running with Cluster mode...

Looks like a plugin issue.  Sometimes this occurs due to bad plugin cache so I would start there and clear it.  https://confluence.atlassian.com/confkb/how-to-clear-confluence-plugins-cache-297664846.html

  Hello, indeed that was the problem.

There was some plugin cached.

Thank you very much for your help.
