A possible fix

A possible fix that is in use on the wikis of the ScoutWiki Network: http://www.scoutwiki.org.

An other site with the same problem:
https://www.mediawiki.org/wiki/Extension_talk:GlobalUsage#Change_display_23718
http://mywiki.everythingfoodanddrink.org/wiki/File:GlobalUsage_screenshot.jpg

Im not sure what this has to do with naming conventions. GlobalUsage should use whatever names are in the $wgLBFactoryConf and $wgConf.

If those configuration variables are not set properly, you will get errors like above. (Yes i am aware that they are slightly confusing config settings...)

The problem is that deep down GlobalUsage uses functions like these: 
WikiMap::getWiki
WikiReference::getDisplayName - Get the the URL in a way to de displayed to the user More or less Wikimedia specific.

Those functions only give correct results if the database names are like enwiki, lang suffix, but not if your database names are like wikien, wiki_en or something completely different.

Well that may be the default, can't you just override that by doing something like:

function wfGetWikiType( SiteConfiguration $conf, $wiki ) {
 // Do whatever you need to do to figure out lang etc
 return( array( 'lang' => $whateverLanguageIs, 'suffix' => $whateverWikiFamilyIs ) );

}

$wgConf->siteParamsCallback = wfGetWikiType;

[That example is untested, I could have mistyped something or misunderstood something]

Case in point, the last line should be,

$wgConf->siteParamsCallback = 'wfGetWikiType';

Our farm uses CommonSettings.php and InitialiseSettings.php
We already tried this:
# ----------------------------------------------------------------------
# Initialisation

$wgLocalDatabases = array(
   'scoutwiki_ar',
   'scoutwiki_cs',
   'scoutwiki_da',
   'scoutwiki_de',
   'scoutwiki_en',
   'scoutwiki_eo',
   'scoutwiki_fi',
   'scoutwiki_fr',
   'scoutwiki_it',
   'scoutwiki_nl',
   'scoutwiki_pt',
   'scoutwiki_sv',
   'scoutwiki_uk',
   'scoutwiki_asso',
   'scoutwiki_media',
);
 
$wgConf->wikis = $wgLocalDatabases;
$wgConf->prefixes = array( 'scoutwiki' );
$wgConf->localVHosts = array( 'localhost' );

require_once "$IP/sites/InitialiseSettings.php";
 
function efGetSiteParams( $conf, $wiki ) {
    $site = null;
    $lang = null;
    foreach( $conf->prefixes as $prefix ) {
        if ( substr( $wiki, 0, strlen( $prefix ) ) == $prefix ) {
            $site = $prefix;
            $lang = substr( $wiki, strlen( $prefix ) + 1 );
            break;
        }
    }
    return array(
        'suffix' => $site,
        'prefix' => $site,
        'lang' => $lang,
        'params' => array(
            'lang' => $lang,
            'site' => $site,
            'wiki' => $wiki,
        ),
        'tags' => array(),
    );
}
 
$wgConf->prefixes = $wgLocalDatabases;
$wgConf->suffixes = $wgLocalDatabases;
$wgConf->siteParamsCallback = 'efGetSiteParams';
$wgConf->extractAllGlobals( $wgDBname );
# -----------------------------------------------

The result is: the site names are empty and the image links link to the local wiki.
