Diagnosis
Determine the list_index for each directory in the Confluence database using the following SQL query:
SELECT * FROM cwd_app_dir_mapping ORDER BY 5;
This error can also occur when the cwd_application and/or cwd_app_dir_mapping tables are empty after a failed XML import. If this is the case, please follow Unable to Log In to Confluence.
Cause
This problem occurs if the list index of your directories is not incremental (0,1,2..), or if the cwd_app_dir_mapping the table does not include a directory with a list-index of 0.
Resolution
- Shutdown Confluence
Update the
cwd_app_dir_mappingtable so that thelist_indexof the directories are in proper incremental order (i.e., 0, 1, 2, ...). You can use the following SQL queries:UPDATE cwd_app_dir_mapping SET LIST_INDEX=0 WHERE ID=<first_id>; UPDATE cwd_app_dir_mapping SET LIST_INDEX=1 WHERE ID=<second_id>; UPDATE cwd_app_dir_mapping SET LIST_INDEX=2 WHERE ID=<third_id>;- Restart Confluence
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.
