Saw this on a new Mediawiki install where all of the optional extensions were selected, LocalSettings.php had been uploaded to the server and that’s as far as it would go.
To fix, open up LocalSettings.php and comment out the line:
require_once( “$IP/extensions/LocalisationUpdate/LocalisationUpdate.php” );
You should now be able to refresh the main page and start using your wiki.
If you have a wiki you may need to change a user’s password from time to time; you can do this from the back end quite easily. First, access mysql:
mysql -u root -p
Log in using your root password. Next, list your databases:
On our test system this shows all of our databases like so:
mysql> show databases;
6 rows in set (0.10 sec)
Select your wiki’s database:
Replace “wiki” in the above with your own database’s name.
UPDATE user SET user_password = MD5(CONCAT(user_id, ‘-‘, MD5(‘newpasswordgoeshere’))) WHERE user_name = ‘usernameofuser’;
If this is successful you should get the following:
Query OK, 1 row affected (0.01 sec)
Rows matched: 1 Changed: 1 Warnings: 0
If something has gone wrong (e.g. a non-existent username) you will get the following instead:
Query OK, 0 rows affected (0.03 sec)
Rows matched: 0 Changed: 0 Warnings: 0
All done! To leave mysql just type “exit”.
