An error occurs when running the demo on the self-built server, when a player joins the room。
stack show as below:

Hi @weixudong,

Thank you for choosing Photon!

If I'm not mistaken you also send an email about this right?
Anyways, there are two solutions to this:

- use serialization protocol v1.8 with Photon Server v5
- remove of "Assets\Photon\Simple"

I have made a change to Simple's send/rcv methods to check for older protocol to handle this (not released yet). Though Simple should not be sending anything if you aren't using any NetObjects in your scene. So that suggests you also have an older Pun2? Be sure to get current, as there were a lot of fast fixes made after Simple was added.

Or, just continue to delete the Simple folder, as it sounds like you aren't using those extensions.

Delete PhotonUtilities as well if you delete Simple.
