I am updating the application to Rails 3.1. Cite often, Firebug will complain about some assets. Here are some errors inserted with Firebug:
"NetworkError: 500 Internal Server Error - http://unstilted.dev/assets/jquery-ui.js?body=1" jquery...?body=1 "NetworkError: 500 Internal Server Error - http://unstilted.dev/assets/admin/pages/file_attachments.js" file_a...ents.js "NetworkError: 500 Internal Server Error - http://unstilted.dev/assets/admin/file_attachments/sortable.js?body=1" sortab...?body=1 "NetworkError: 500 Internal Server Error - http://unstilted.dev/assets/jquery.js?body=1"
Refreshing the page will result in different assets showing the same error. When I copy and paste the URL, I see the files in order.
I use:
- Ubuntu 11.04
- Apache + Passenger 3.0.9
How to fix it?
UPDATE : log file
In this particular case, jquery-ui.js showed an error in Firebug. My log file looked like this:

Seems to have missed jquery-ui.js !
UPDATE October 1, 2011
I tried this with a passenger start ( passenger start ), as it seems to give a more descriptive error. This is what happens when I try to download only the jquery.js file and press CTRL-R several times to refresh my browser and reload this resource.
