检查下你的ks_cls/ubbfunction.asp文件里有没有这一句：

re.pattern="\[media=(swf),*([0-9]*),*([0-9]*),*([0-1]*)\]([^\[]*)\[\/media\]"
if re.Test(strcontent) then strcontent= re.replace(strcontent,"<object classid=""clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"" width=""$2"" height=""$3""><param name=""autostart"" value=""$4"" /><param name=""src"" value=""$5"" /><embed controller=""true"" width=""$2"" height=""$3"" src=""$5"" autostart=""1""></embed></object>")
