Hi everyone
I have upgraded from 3.2 to 4.2 but I keep getting an annoying error. I have
tried to find the solution in the forums etc but with no luck.
When I deploy my application I get the following generic error:
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented it
from fulfilling this request.
exception
