CKEditor：无法输入编辑器字段

Question

我使用的是CKEditor，但我无法在字段中输入任何文字，也无法使用任何菜单项。 我使用以下代码加载编辑器：

<textarea name="editor_beschreibung"></textarea>
<script>
    CKEDITOR.replace('editor_beschreibung');
</script>

这是我的配置的外观：

CKEDITOR.editorConfig = function( config ) {
	// Define changes to default configuration here.
	// For complete reference see:
	// http://docs.ckeditor.com/#!/api/CKEDITOR.config

	// The toolbar groups arrangement, optimized for two toolbar rows.
	config.toolbarGroups = [
		{ name: 'clipboard',   groups: [ 'clipboard', 'undo' ] },
		{ name: 'editing',     groups: [ 'find', 'selection', 'spellchecker' ] },
		{ name: 'links' },
		{ name: 'insert' },
		{ name: 'forms' },
		{ name: 'tools' },
		{ name: 'document',	   groups: [ 'mode', 'document', 'doctools' ] },
		{ name: 'others' },
		'/',
		{ name: 'basicstyles', groups: [ 'basicstyles', 'cleanup' ] },
		{ name: 'paragraph',   groups: [ 'list', 'indent', 'blocks', 'align', 'bidi' ] },
		{ name: 'styles' },
		{ name: 'colors' },
		{ name: 'about' }
	];

	// Remove some buttons provided by the standard plugins, which are
	// not needed in the Standard(s) toolbar.
	config.removeButtons = 'Underline,Subscript,Superscript';

	// Set the most common block elements.
	config.format_tags = 'p;h1;h2;h3;pre';

	// Simplify the dialog windows.
	config.removeDialogTabs = 'image:advanced;link:advanced';
	
	//size
	config.height = '450px';
	
	config.removePlugins = 'elementspath';
};

我希望有人可以帮我解决这个问题。 感谢
