Hi, I'm upt o install retrospectiva on my centOS 5 machine. Therefore, i installed ruby 1.9.1 (ruby 1.9.1p376 (2009-12-07 revision 26041) [x86_64-linux]) and following gems: *** LOCAL GEMS *** actionmailer (2.3.5) actionpack (2.3.5) activerecord (2.3.5) activeresource (2.3.5) activesupport (2.3.5) fastthread (1.0.7) mysql (2.8.1) passenger (2.2.10) rack (1.0.1) rails (2.3.5) rake (0.8.7) sinatra (0.9.4) Furthermore, I put the passenger module into my apache conf LoadModule passenger_module /usr/local/lib/ruby/gems/1.9.1/gems/passenger-2.2.10/ext/apache2/mod_passenger.so PassengerRoot /usr/local/lib/ruby/gems/1.9.1/gems/passenger-2.2.10 PassengerRuby /usr/local/bin/ruby A vhost exists for /pathToRetrospectiva/public . If I call the URL for my retrospectiva Host, I get the error "Ruby on Rails application could not be started" Error message: invalid byte sequence in US-ASCII Exception class: ArgumentError The listed Backtrace entries (30 rows) aren't helpfull for me. Does anyone know, how this error can be solved? If the backtrace is required, pls ask for it. alex -- Posted via http://www.ruby-forum.com/.
