Anything is better than "something went wrong". It is quite possibly the stupidest error message every created, we know something went wrong because whatever we tried to do errored out. The best description I've seen of it was in a book draft:

  When web UI developers die they go to what appears to be waiting area before
  the gates of paradise.  However no matter what they do to get in, anything
  they try just pops up a message saying "Something went wrong".  No other
  information, just "Something went wrong" over and over again.  Then they
  wonder why there are flames and screaming all around them...
