Problem

After importing a space, a user may see the following error when visiting Confluence:

Error occurred during template rendering: Invocation of method 'getRenderedParam' in class
com.atlassian.plugin.web.model.DefaultWebParam threw exception java.lang.NullPointerException at
template/includes/menu-macros.vm[line 67, column 50]. Contact your administrator for assistance.

Diagnosis

Environment

• Confluence 5.7
• Other versions of Confluence may be affected

Diagnostic Steps

1. Run the following command against the database.

   select * from spaces where spacename is NULL;

2. If results are returned, please proceed below.

Cause

A space has been imported into Confluence that has no Space Name. CONFSERVER-39517 - Space Imports with SpaceName the same as SpaceKey cause Template NullPointerException

Resolution

Change Space Name

1. Open your Confluence instance;
2. Go to Space > Space Directory;
3. Look for spaces with the name set as 'Undefined';

4. Change the space name.

Modify Data

1. Stop Confluence

2. In the database, run:

   update spaces set spacename='SPACE_NAME' where spaceid=XXXXXX; 

   Always back up your data before performing any modifications to the database. If possible, test any alter, insert, update, or delete SQL commands on a staging server first.

   Where XXXXXX is the spaceid from the results returned in your Diagnosis, and the SPACE_NAME is set to the desired space name.

3. Start Confluence

4. Rebuild the search index
