Revision as of 21:33, 2 October 2014

  • A database query error has occurred. This may indicate a bug in the software.

There are a number of reasons for this error. To get more detail add the following line to your LocalSettings.php

$wgShowSQLErrors = 1;

Now reproduce the error.

The last time I came across this issue I got an error saying that the 'searchindex' table needed to be repaired. The steps I took to fix this issue are as follows:

  1. Backup the searchindex tablw with mysqldump. (mysqldump -u user -p --databases mediawiki --tables searchindex > searchindex.sql)
  2. Truncate the table (truncate searchindex;)
  3. Verify the table is empty (select * from searchindex;)
  4. Run php rebuildall.php (this rebuilds all the indexes)
  5. You may have to run rebuildImages.php also (in my case this wasn't necessary)
