This topic deals with the request for plugin-per-user settings as per http://forums.b2evolution.net/plugin-development-opportunities

From @fplanque]

@achillis Yes, we'll be checking on how to make that work for plugin-per-user settings as shown on your screenshot above.

Of you have another place where it doesn't work, please be so kind and screenshot it.

@mgsolipa looking at https://github.com/b2evolution/b2evolution/commit/9a1fceb8dbc77f10ec25c382aa23bfb497a51b12

I am not sure if this is correct or incorrect behavior;

When developing a plugin both settings needs to be specified. If Global settings are not defined then it breaks. This is because with Widgets it looks for Settings and not param_settings? if the user does not specify matching sets with GetDefaultSettings together with get_widget_param_definitions the following result with widget type settings:

function GetDefaultSettings( & $params )
	{ 
		global $app_version;
		
		return array(
		
			
			'sample_sets' => array(
				'label' => T_('Dynamic Settings'),
				'note' => T_('Click to add another set'),
				'type' => version_compare( $app_version, '6.6.5', '>' ) ? 'array:array:string' : 'array',
),
)
}

function get_widget_param_definitions( $params )
	{ 
		global $app_version;
		
		return array(
		
			
			
			'sample_sets' => array(
				'label' => T_('Dynamic Settings'),
				'note' => T_('Click to add another set'),
				'type' => version_compare( $app_version, '6.6.5', '>' ) ? 'array:array:string' : 'array',
),
)
}

then the following error occurs.
