Bildergalerie w3concepts.gallery
Verfasst: Do 5. Jun 2008, 19:20
Ich habe mit Andreas' Hilfe seine Bildergalerie unter 4.8.4 mit PHP5 zum Laufen gebracht. Es geht um das Modul Bildergalerie w3concepts.gallery.v1, zu finden unter http://forum.contenido.org/viewtopic.ph ... sc&start=0
Hier ist die Version, die mit 4.8.x läuft. Ob die abwärtskompatibel ist, weiß ich nicht, aber falls nicht, kann ja die andere Version benutzt werden.
