Body: <p>I have the correct image asset source for S3 and also a local folder. Neither folder contents show (they were previously) and I see an "unknown error occurred" popup. I've tried turning off image transforms, increasing my PHP memory limit and simplifying my templates but I haven't had any luck</p>

Comments.Text: The underlying error message for "unknown error occurred" will be in your `craft/storage/runtime/logs` files.  You can start there to help debug this.

  Check your craft.log and phperrors for clues, wild guess is that you're running out of memory.
  
  If that is the case you should increase `memory_limit` in PHP.
