      Error:
  Conversion failure in entity type [#name#] attribute [#name#]; No converter found capable of converting from type [org.molgenis.data.support.DynamicEntity] to type [java.lang.String]

  • If users or groups were giving special permissions on the Settings Manager Plugin, these permissions should be set again for the replacement Settings Plugin. The plugin itself is replaced automatically.
