After upgrade Error: the JSON object must be str, bytes or bytearray, not NoneType on login

Hello,
After upgrading cyberpanel to latest version if you login with non-admin user we get this error:

1537×981 61.5 KB

This only happens when you login as non-admin user. Any advice? We are on

Current Version2.1
Latest Version2.1
Build 1
Latest Build 1

Thank you for your help.

If anyone has the same problem you will have to recreate ACL and set new ACL to users then it will work fine.

Yes, just recreate the ACL and assign them to users and delete old ACL. (This is for custom ACL only and already discussed in our facebook group)
