It looks like the ContactPage extension was forked into a ContactPageFundraiser variant, but this has led to nothing but bitrot and confusion.
The ContactPage extension is being maintained while ContactPageFundraiser is not. I'd suggest removing these lines from CommonSettings.php:
include( "$IP/extensions/ContactPageFundraiser/ContactPage.php" ); $wgContactUser = 'Storiescontact';
And in InitialiseSettings.php, replace the relevant section of code with:
'wmgContactPageConf' => array(
'default' => false,
'foundationwiki' => array(
'wgContactUser' => 'Storiescontact',
'wgContactIncludeIP' => false,
),
// bug 15624
'nlwiki' => array(
'wgContactUser' => 'WikiAdmin',
'wgContactSenderName' => 'Contactformulier op nl-Wikipedia',
'wgContactIncludeIP' => true,
),
),Version: unspecified
