ERROR 500 Cyberpanel

Hello friends,

when I enter https://IP:8090 I get error 500 .

I turned on debug on /usr/local/CyberCP/CyberCP/ and systemctl restart lscpd. but nothing happened.

I checked logs on /home/cyberpanel/stderr.log and find this:

2020-09-02 08:31:36.206541 [4397] packetLen < 0
Traceback (most recent call last):
File “/usr/local/CyberCP/CyberCP/”, line 16, in

File “/usr/local/CyberCP/lib/python3.8/site-packages/django/apps/”, line 83, in populate
raise RuntimeError(“populate() isn’t reentrant”)
RuntimeError: populate() isn’t reentrant

I don’t have further information on this time.
is there any way to find and fix this problem?

thanks in advanced

I tried to upgrade (re-install) CP with:

sh <(curl || wget -O -

and problem solved.
