hitman6003 Posted February 14, 2007 Share Posted February 14, 2007 It means that where ever you are trying to instantiate the zip_file class, you aren't including the file that contains the archive class. Quote Link to comment Share on other sites More sharing options...

hitman6003 Posted February 14, 2007 Share Posted February 14, 2007 There's no having a go at it. Just include the file that has the "archive" class in your script. Quote Link to comment Share on other sites More sharing options...
