Hi all

I just got a “We’re sorry, but something went wrong.” message while  
developing my Rails app. I didn’t expect such a message to be displayed  
in development mode - is this normal? And if so, in what cases will be  
displayed an exception error and when this 500 message?

Thanks for information.  
Josh

I also had this error in development mode.  
It was a problem of incorrect number of ‘end’  
I found the error thanxs to the log files.

Yeah… whenever you get that it’s because something’s horribly wrong in  
one  
of your classes, so horribly wrong that Rails can’t get started.

That could be caused by all sorts of things. Look in log/  
development.log for clues.
