[vijay kumar]

Dear Member,
I am not getting the opac and intranet in browser
when type localhost:80 automatically goes to     maintenance.pl
                          http://localhost/cgi-bin/koha/maintenance.pl
and when type localhost:8080 it shows
                              production mode - trapped fatal error
My zebraserver and yaz client is running properly and installed all
perl model properly...........

So please guide me..................

Thanks
