== !ControllerException ==

'''ERR_CLASS_NOT_FOUND'''
  Lepton uses a relaxed loading of controllers to allow for specific controllers to be inserted through extensions or the application folder. Therefore a missing controller file won't throw an exception. However, if the matching class can't be found, an exception will be thrown.

'''ERR_METHOD_NOT_FOUND'''
  This happens if you call on a controller that hasn't got neither the requested method nor the unknown method defined as public members.

== !UploadsException ==
''Since these exception codes are mapped against the PHP error codes, they are prefixed with `UPLOAD_`.''

'''UPLOAD_ERR_CANT_WRITE'''
  This happens if the upload folder is not writable. Check your permissions.

'''UPLOAD_ERR_EXTENSION'''

'''UPLOAD_ERR_FORM_SIZE'''

'''UPLOAD_ERR_INI_SIZE'''
  The uploaded file is too large

'''UPLOAD_ERR_NO_FILE'''
  There's no file uploaded.

'''UPLOAD_ERR_NO_TMP_DIR'''
  There is no temporary directory available to upload the files into. Take a look at your PHP installation, and make sure that the upload directory is specified.
