Issues Deploying Rails App

Hi there,

I'd like to deploy my app and I followed a long tutorial (not the GoRails one badly :( ) but I managed to put it on the server and running with Capistrano. DB is postgre and OS is Debian (is this a problem and better get on Ubuntu..?). I get the error message "An unhandled lowlevel error occurred. The application logs may have details." Where could it come from?

Thank you and have a good night/day :)

I finally tried to do it with your tutorial but I'm blocked at some point, just when I type cap production deploy

Thank you if you get some time to take a look... I was on rvm but uninstalled it and put rbenv.
I'm so frustrated since I got so close..! ^{^}

Also on the server side I tried to do rbenv install 2.6.1 and I got :

I don't know why I paid to get here because nobody answers me and also the only video I needed to see is free to watch for anyone on YouTube... Please tell me what advantages do I really get from this subscription?

You can try RUBY_CONFIGURE_OPTS=--disable-install-doc rbenv install 2.6.3

instead of rbenv install 2.6.3
