The string containing a debug mode or an array of available debug modes. The following values are supported:
 
| Value | Description |

| **popup** | All the messages will be shown in a popup window. |
| **console** | All the messages will be logged in a browser console (e.g. Firebug) if it is available. |
| **alert** | All the messages will be shown in alerts. |

When the [debug](https://www.aurigma.com/docs/us8/FH_T_J_$au_debug.htm.md) class is about to display a message, it uses the first mode specified in this array. If it is failed, the next mode is used until the message is displayed correctly.
