In connection with an upgrade and the setup check the wiki may temporarily made inaccessible to an audience due to:


 * ERROR_SCHEMA_INVALID_KEY message will appear to require an administrator to take action to minimize any possibility of data loss due to changes in the database structure.
 * MAINTENANCE MODE once the upgrade is in progress, the information screen will change its appearance and inform the audience about the maintenance status.
