具体提示：This connector is disabled. Please check the "editor/filemanager/connectors/php/config.php" file

Limesurvey采用的FCK编辑器，这个编辑器默认禁用了上传，解决办法是：

找到这个文件，具体在：

./admin/scripts/fckeditor.2641/editor/filemanager/connectors/php/

修改config.php，找到

// SECURITY: You must explicitly enable this "connector". (Set it to "true").
// WARNING: don’t just set "$Config[‘Enabled’] = true ;", you must be sure that only
//  authenticated users can access this file or use some kind of session checking.
$Config[‘Enabled’] = false ;

将false改成true即可
