redmine: Application error Rails application failed to start properly

Das Problem lag an der .htaccess Datei. Diese kann wie folgt aussehen, damit sie funktioniert:

# General Apache options
<IfModule mod_fastcgi.c>
 AddHandler fastcgi-script .fcgi
</IfModule>
<IfModule mod_fcgid.c>
 AddHandler fcgid-script .fcgi
</IfModule>
<IfModule mod_cgi.c>
 AddHandler cgi-script .cgi
</IfModule>
Options +FollowSymLinks +ExecCGI

# If you don't want Rails to look in certain directories,
# use the following rewrite rules so that Apache won't rewrite certain requests
#
# Example:
#   RewriteCond %{REQUEST_URI} ^/notrails.*
#   RewriteRule .* - [L]

RewriteBase /
RewriteRule ^(javascript|stylesheets|themes|images|help|plugin_assets|favicon\.ico).* - [L]

# Redirect all requests not available on the filesystem to Rails
# By default the cgi dispatcher is used which is very slow
#
# For better performance replace the dispatcher with the fastcgi one
#
# Example:
#   RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
RewriteEngine On

# If your Rails application is accessed via an Alias directive,
# then you MUST also set the RewriteBase in this htaccess file.
#
# Example:
#   Alias /myrailsapp /path/to/myrailsapp/public
#   RewriteBase /myrailsapp

RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]

#RewriteRule ^$ index.html [QSA]
#RewriteRule ^([^.]+)$ $1.html [QSA]
RewriteCond %{REQUEST_FILENAME} !-f
<IfModule mod_fastcgi.c>
 RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
</IfModule>
<IfModule mod_fcgid.c>
 RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]
</IfModule>
<IfModule mod_cgi.c>
 RewriteRule ^(.*)$ dispatch.cgi [QSA,L]
</IfModule>

# In case Rails experiences terminal errors
# Instead of displaying this message you can supply a file here which will be rendered instead
#
# Example:
#   ErrorDocument 500 /500.html

ErrorDocument 500 "<h2>Application error</h2>Rails application failed to start properly"
