My website in a production environment(locally hosted) doesn't give me a SERVER ERROR 500 when I navigate through the archives, but once uploaded here on my domain it's returning this error. The following link is an example :
Fails http://www.coaltober.com/archive/2012/05
Works http://www.coaltober.com/archive/2012/
I wanted to diagnose this behaviour, but the error logs empty, any tips?
