Symfo2 - fm_elfinderbundle +IvoryCkeditorBundleIntégration

Question

我正在尝试将 elfinderbundle 与 ivoryCkeditorbundle 整合在一起，并且有效！

但是，当我尝试上传图片时，收到错误

  

信令：无法访问后端。

以下是我的不同配置文件：

config.yml

ivory_ck_editor:
default_config: default
configs:
    default:
        filebrowserBrowseRoute: elfinder
        filebrowserBrowseRouteParameters: []
