can anyone know how to solve it.

have you tried localhost instead of ipaddress?

I’m also trying to deploy my app at hostgator and I’m facing this error:

undefined method `paginate_by_sql’

I have installed will_paginate both as a gem and plugin and in my local
configuration the app works fine. Any idea?

thank you very much for your reply
yes I try too but I got the same error.maybe if you had made a success
on deploying a RoR application locally develop and deploy on their linux
server please post an instructions on how.

Finally after a weekend I have my rails app up and running.

I use exactly the same version as hostgator for rails, gems etc. So I
did nothing like freezing rails or gem. My problem was the above. I was
always getting an error as rails server didn’t include the path of
/vendor/plugins. So we added this little magic line on my
/config/environment.rb

“config.load_paths += %W( #{RAILS_ROOT}/vendor/plugins )” and everything
works fine right now.

no .htaccesses added!

Can you please elaborate detail by detail from start on how you upload
the application.what is your development environment.how you upload your
application through ftp or ssh.what modification you did.

again thank you very much

the process was really very simple. I use the same rails and gem
versions so I didn’t have to freeze my project. I created a new RoR
application (cpanel), I uploaded my app and replaced the files from the
app that I had just created (~/etc/rail_apps/sample_app/). Then I
created a symbolic link from the cpanel, I added the line from the above
comment to my config/environment.rb and just everything works
