Hi,

I followed this [[http://www.redmine.org/projects/redmine/wiki/Redmine_on_CentOS_installation_HOWTO]] step by step, first i had some problems with users and groups. Plesk has its own users, different from 'apache' so i had to modify it according to them.

That took me a step further, but I'm again stuck. I googled for the problem, found this:
http://www.redmine.org/issues/4610

I allready tried to:
- Disable all cgi options for the subdomain (using plesk cp)
- Removing .htaccess from public folder (if I do this trying to access the web returns a forbidden error)
- changing mod_cgi.c to mod_cgid.c (this launches a different error, but i suspect i'm going back not forward)

In my browser i get the following msg:
Application error
Rails application failed to start properly
In the error_log file i get:
[Wed Jul 04 14:04:14 2012] [error] [client .*..*] /var/www/vhosts/*.com/redmine/vendor/rails/actionpack/lib/action_controller/cgi_process.rb:22:in `__send__'
