Looks like your app is trying to use memcache but it couldn’t talk to
the memcache server.

Fred

Hello,
As per your post, i think you are trying to run application on
the already used port. so try to use some alternate port and try to run
application.

Hi Fred,

I can’t telnet localhost 112111 either. I will dig in and notify what
happened. Thank you for the prompt suggestion

Ahmet

referring to HELP_BASKET

It doesn’t work - it is causing an error.

You are going to have to learn how to solve these errors.

This message has been scanned for viruses and
dangerous content by MailScanner, and is
believed to be clean.

By the adventrous KETE installation on Ubuntu server, 500 error is
gone, but I’m missing still some crucial intallation steps (?) Upon
ruby script/server command the server generates the following error.
The development database is empty. I entered in to basket table just a
dummy name.

Thanks being patient with me.
