Redmine

Hello,

I'm trying to install Redmine on 1and1, I followed the official guide
installation and it seems that everything went perfectly when installed.

I created my own installation of Ruby in a directory type
$HOME/bin/ruby, and I created symbolic links from the "public" of
redline: ln -s $HOME/redline/public/ $HOME/midomain.com/*

But my problem is accessing midomain.com, I get error 500 and my
log files are empty.

cgi_process.rb:22:in `__send__': undefined method `env_table' for nil:NilClass (NoMethodError)

Can anyone help?

Thank you very much

NOTE 1:
I'm change all head script:
#!/env/bin ruby
For
#!$HOME/bin/ruby/bin/ruby
For use my ruby installation.
