I have enabled the flagged revs, and promoted users, but get an error updating pages. I am assigning this to Aaron, as I think he will know what the solution is.

[root@zwinger ~]# cd /home/wikipedia/common/php-1.5/ && php extensions/FlaggedRevs/maintenance/updateLinks.php --updateonly=pages dewikiquote
Populating and correcting flaggedpages/flaggedpage_config columns

@Rob: '$wgFlaggedRevTags = array( 'geprüft'=>1 );' won't work. It wants simple ASCII names only. The actually UI value is controlled by the message file. I'd rename to "quality" or something.

According to the discussion on wikiquote, i think their intention is to have the following settings:
$wgSimpleFlaggedRevsUI = true;
$wgFlaggedRevsOverride = false;
$wgFlaggedRevTags = array( 'accuracy'=>2 );
$wgFlaggedRevsAutopromote = false;
$wgFlaggedRevsPrecedence = false;
And some values can simply be removed because its the default setting
$wgFlaggedRevValues = 2; (default, currently set to 1)
$wgFlaggedRevsLowProfile = true; (default)

At the moment 'checked' is used as tag which has no default messages. Only accuracy, depth and style are well translated tags, so accuracy should be used instead

We would really happy if you could change to the settings in comment #3 as soon as possible. At this time we cannot use this flaggedRevs because it doesn't work. Users are confused about it.

Done.
