This has been discussed on the mailing list about 6 weeks ago (though I
was not subscribed at that time)
Special:MostLinkedPages appears to be broken:
Fatal error: Call to a member function getPrefixedDBkey() on a
non-object in mediawiki/includes/specials/SpecialMostlinked.php on
line 64
This is indeed caused by a bug in this PHP file. It can be fixed by
changing the original code:
function makeWlhLink( &$title, $caption,
&$skin ) {
$wlh = SpecialPage::getTitleFor( 'Whatlinkshere',
$title->getPrefixedDBkey() );
return $skin->makeKnownLinkObj( $wlh, $caption );
}
to:
function makeWlhLink( &$title, $caption,
&$skin ) {
$wlh = SpecialPage::getTitleFor( 'Whatlinkshere', $title );
return $skin->makeKnownLinkObj( $wlh, $caption );
}
It took 5 minutes to find and fix the bug, and 55 minutes to submit it
to bugzilla (apparently the site seems to be under heavy load).
