re-installed J3 now I get error in HTML editor

I had to re-instll Joomla 3, now I get the following error.

Fatal error: Call to undefined method stdClass::onDisplay() in /home3/mcross/public_html/libraries/cms/editor/editor.php on line 459

The following is from 469 on:

protected function _loadEditor($config = array())
{
// Check whether editor is already loaded
if (!is_null(($this->_editor)))
{
return;
}

// Build the path to the needed editor plugin
$name = JFilterInput::getInstance()->clean($this->_name, 'cmd');
$path = JPATH_PLUGINS . '/editors/' . $name . '.php';

if (!is_file($path))
{
$path = JPATH_PLUGINS . '/editors/' . $name . '/' . $name . '.php';
if (!is_file($path))
{
JLog::add(JText::_('JLIB_HTML_EDITOR_CANNOT_LOAD'), JLog::WARNING, 'jerror');
return false;
}
}

// Require plugin file
require_once $path;

// Get the plugin
$plugin = JPluginHelper::getPlugin('editors', $this->_name);
$params = new JRegistry;
$params->loadString($plugin->params);
$params->loadArray($config);
$plugin->params = $params;

// Build editor plugin classname
$name = 'plgEditor' . $this->_name;

if ($this->_editor = new $name($this, (array) $plugin))
{
// Load plugin parameters
$this->initialise();
JPluginHelper::importPlugin('editors-xtd');
}
}
}

Hello

OK, but maybe give some more information about this error in regards to FLEXIcontent ??

- you get this in FLEXIcontent item form ?
or in FLEXIcontent category edit form ?
or in both of them ?

- do you get this error in other components using the editor,
e.g. in contacts component
(open any page that loads the HTML editor)
