Sorry - my wiki uses "simpleCatcha". I've just tried to change to  
"MathCatcha" following the instructions in


(version from May 6 2011)

and edited only "LocalSettings.php". That led to the error message

----------------- error -------------------

Es ist ein Datenbankfehler aufgetreten. Der Grund kann ein  
Programmierfehler sein. Die letzte Datenbankabfrage lautete:

    (SQL-Abfrage versteckt)

aus der Funktion "MathRenderer::_recall". Die Datenbank meldete den  
Fehler "1267: Illegal mix of collations (latin1_german2_ci,IMPLICIT) and  
(utf8_general_ci,COERCIBLE) for operation '=' (db2.variomedia.de)".


There may be some inconsistency in the database - who can help, what can  

I can edit the database via phpMyAdmin (or other tools).

Viele Gruesse!
