Modx Revolution 2.4.0 - Manager - Files Tab (500 - Internal Server Error)

Hi to All,

Does anyone encounter a problem in Manager > Files accessing this tab causes 500 Internal Server Error?

Everytime I click the Filesystem folder I'm getting error. My prediction is the permission. But I'm not sure though.

I attached screenshot of the console error.

I hope someone has solution for this.

Thank you very much in advance.
