Hi Ann

I decided to reinstall Confluence and restore from the previous days backup. Everything is now fine.

It was probably a database entry errror somewhere.

The error you posted is similar to what is in this knowledgebase article, where the same symptom was reported: Error 500 while trying to access some admin functions (NoClassDefFoundError com.atlassian.upm.osgi.impl.Versions)

* Please check the log for entries related to the admin page URL where you are getting the error (admin/viewgeneralconfig.action). That will give us an idea what is happening when you go to the page.
* Please let me know what database management system you are running, for example PostgreSQL, MySQL, Oracle or MS SQL.
