Can't insert custom configuration

I have this PHP code, Everything works except the configurations from sidebar_config.js, which can be seen here: http://kodetslyst.dk/files/sidebar_config.js.

$oFCKeditor = new FCKeditor('FCKeditor1');
$oFCKeditor->Config['CustomConfigurationsPath'] = "files/sidebar_config.js";
$oFCKeditor->BasePath = '/fckeditor/';
$oFCKeditor->Width = '800';
$oFCKeditor->Height = '630';
$oFCKeditor->ToolbarSet="Default";link
$oFCKeditor->Config['EnterMode'] = 'br';
$oFCKeditor->Config['DisableFFTableHandles'] = 'false';
$oFCKeditor->Value = $content1;
$oFCKeditor->Create();
