Moin!

Ich betreibe die MediaWiki-Version: 1.5.7.
Die DynamicPageList2 hat bei mir einen Fehler ausgeworfen.
Deshalb habe ich diese ("alte") DynamicPageList für mich geringfügig erweitert:


  • Caching ausgeschaltet


  • Sortierung nach Titel
    Neuer Parameterwert: ordermethod=title


  • Zusatz des Datums der letzten Änderung (hinten dran in Klammern)
    Neuer Parameter: addpagetoucheddate=true|false (default=false)

Hallo, wo kann man denn Hilfe zum Einbinden der Extension finden? Denn wenn ich in meiner LocalSettings die Zeile include("extensions/DynamicPageList/DynamicPageList.php"); einfüge, erhalte ich nur eine weiße Seite und das Wiki ist dann leider nicht mehr da.
