When I visit the app in the browser it says Application Error. I checked the logs and here's what I found:

Two weeks ago when I created this staging dyno there was no problem. Today I just added an html erb file, push the changes and it gives me the errors above.

Any help?

Answer 1

Found the problem... the cache in heroku dyno needs to be purged. Heroku made a plugin that can do just that. Install it:

$ heroku plugins:install heroku-repo

And run:

$ heroku repo:purge_cache -a appname

Then commit something or run heroku repo:reset and deploy again.

Answer 2

The cache in heroku dyno needs to be purged. Heroku made a plugin that can do just that. Install it:

$ heroku plugins:install heroku-repo

And run:

$ heroku repo:purge_cache -a $APPNAME

Then deploy again.
