Several times we got database error like the following one: Es ist ein Datenbankfehler aufgetreten. Der Grund kann ein Programmierfehler sein. Die letzte Datenbankabfrage lautete: transl: A database error occurs. Maybe, the cause could be a programmer's mistake. The last query was: (Die SQL-Datenbankabfrage ist verborgen.) transl: The sql query is hidden. aus der Funktion „DatabaseBase::update“. Die Datenbank meldete den Fehler „1062: Duplicate entry '5567-2-Celsius' for key 'wl_user' (10.64.16.8)“. transl.: from the function „DatabaseBase::update“. The database returned the error message: „1062: Duplicate entry '5567-2-Celsius' for key 'wl_user' (10.64.16.8)“.
Hi Roland, please see http://www.mediawiki.org/wiki/Manual:How_to_debug#SQL_errors for how to display the hidden SQL query, and paste it here. Thanks!
Hi Andre, because Wikivoyage is a WMF project we have no access to LocalSettings.php
Ah. Wasn't clear to me that it's about Wikivoyage, sorry. Thought this is a private MediaWiki installation... :)
Was this Special:MergeAccount or Special:UserMerge?
I think it was Special:MergeAccount. But this service was stopped some time ago to our wiki. It seems that the error occurs if users edited the user pages of the account to merge.
