FCKeditor won't show in Drupal

Hey there,
I installed FCKeditor v. 2.6.3 in Drupal and made the following adjustments:


But the editor won't show, neither in Firefox nor in IE. But the source code tells me that the editor is loaded:

<div id="fck_oFCK_1"><textarea id="oFCK_1"></textarea></div>
<a href="javascript:Toggle('oFCK_1','edit-body','Zum einfachen Text Editor umschalten','Zum Rich-Text Editor umschalten');" id="switch_oFCK_1" style="display:none">Zum einfachen Text Editor umschalten</a>
<script type="text/javascript">window.setTimeout("CreateToggle('edit-body','oFCK_1', 1);",100);
</script>
<script type="text/javascript">
var oFCK_1 = new FCKeditor( 'oFCK_1' );
oFCK_1.BasePath = '/drupal/modules/fckeditor/fckeditor/';
oFCK_1.Config['CustomConfigurationsPath'] = "/drupal/modules/fckeditor/fckeditor.config.js";
oFCK_1.Config['TextareaID'] = "edit-body";
oFCK_1.ToolbarSet = "DrupalBasic";
oFCK_1.Config['SkinPath'] = oFCK_1.BasePath + "editor/skins/default/";
oFCK_1.Config['DefaultLanguage'] = "en";
oFCK_1.Config['AutoDetectLanguage'] = true;
oFCK_1.Height = "420";
oFCK_1.Config['ToolbarStartExpanded'] = true;
oFCK_1.Width = "100%";

oFCK_1.Config['EnterMode'] = 'p';
oFCK_1.Config['ShiftEnterMode'] = "br";
oFCK_1.Config['FontFormats'] = "p;div;pre;address;h1;h2;h3;h4;h5;h6";
oFCK_1.Config['FormatSource'] = true;
oFCK_1.Config['FormatOutput'] = true;
oFCK_1.Config['LinkUpload'] = false;
oFCK_1.Config['ImageUpload'] = false;
oFCK_1.Config['FlashUpload'] = false;
oFCK_1.Config['LinkBrowser'] = false;
oFCK_1.Config['ImageBrowser'] = false;
oFCK_1.Config['FlashBrowser'] = false;
oFCK_1.Config['EditorAreaCSS'] = "/drupal/sites/all/themes/controled/style.css,/drupal/modules/fckeditor/fckeditor.css";</script>

What did I do wrong?
