原因

The confluence.cfg.xml file is missing a line or is corrupt.

ソリューション

  1. Confluence を停止します。
  2. Back up your Confluence home directory. The <confluence_home> directory is the path defined in the following file: <confluence_install>/confluence/WEB-INF/classes/confluence-init.properties
  3. Examine confluence.cfg.xml and check that the attachments.dir property looks like this:

        <property name="attachments.dir">${confluenceHome}/attachments</property>
    

    See the bug report  CONF-19171 - Getting issue details... STATUS  to improve the handling of this error.

  4. Confluence を起動します。
