Redmine

I just write this info for avoiding that somebody else loses as much time as I have wasted in this issue.

Situation. Suddenly, the application does not start. All services up and running (Apache, MySql, Mongrel...), everything seems to be in its right place but when you try to access to redmine you receive following errors directly in browser or in apache log files:

• 502 proxy error
• The proxy server could not handle the request GET /redmine/.
• Testing httpd.conf....Errors reported here must be corrected before the service can be started
• Reason: Error reading from remote server

There is no trace in redmine log files about what is happening.

SOLUTION: review configuration language files. In my case, en.yml included in plugin had an error. It happens too if the redmine/config/locales/en.yml (if using English) has some error, like a quote not closed.

To Consider: Where could be found some track about the incident? redmine? rails?
