While trying to start Unicorn, with the command $: sudo service unicorn_myapp start
I get the following result.
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this...
I sent a ticket for this, but I promise to post the solution.
I re-entered the a2ensite command and got the message site coolaberate.com is already enabled.
NameVirtualHost *:80 file are OK?
