I locate my redmine webite on dreamhost shared-host. It works well in the first 8 months. But recently I meet 404 Page not found frequently when I post a topic in the forum, or create new issues. This weekend I decide to dig the bug.
The problem looks like this in redmine/log/production.log

In the first paragraph, I create an issue. After that the passenger raise an "internal_error", and would like to find public/internal_error.html. Of course this file isn't exist, it's redmine/public/500.html instead. So I get a 404 error, public/404.html is rendered. In the 3rd paragraph, I refresh the page, and get the issue detail page correctly.
I contact the tech support of dreamhost, but the guy refuse to support problems of redmine. damn... I google this problem, many others met it but have no solutions given in their topics, such as
http://discussion.dreamhost.com/thread-130022.html (The tech support of dreamhost is just so so..)
http://groups.google.com/group/phusion-passenger/browse_thread/thread/c04394c2bf8440f6
http://railsforum.com/viewtopic.php?id=36826 (not completely the same)
They're the motion of writing this blog :)
OK, I must DIY now. I know almost nothing about rails, haha. So the breaking point is the 404 page.
1. copy 500.html to internal_error.html to avoid 400 error
After this step, the log looks correctly, but I get a internal_error.html rendered. Actually, I wish it still tell me something more about this error.

I can simply click refresh to get the right page. Why not do it automatically?
2. add this code into the header of redmine/public/internal_error.html
<! DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd" > < head > < META HTTP-EQUIV ="refresh" CONTENT ="0" > </ head > < html > < title > Redirect </ title > < body > < h1 > I can not wait to refresh... </ h1 > < form > < input type ="button" onClick ="history.go(0)" value ="Refresh" > </ form > </ body > </html>
Oh nice, when the passenger raises 500 error, it will not invoke public/500.html, but call my custom public/internal_error.html, and refresh to the right page immediately.
It's nothing but a small trick. I hope it can help others who meet the same problem :)
