/opt/alt/python36/bin/lswsgi: No such file or directory

I am facing this error 503 Service Unavailable The server is temporarily busy, try again later! the error log is... [QUOTE]/usr/local/lsws/fcgi-bin/lswsgi_wrapper: line 18: /opt/alt/python39/bin/lswsgi: No such file or directory /usr/local/lsws/fcgi-bin/lswsgi_wrapper: line 18: /opt/alt/python39/bin/lswsgi: No such file or directory
how can I solve this issue? I have updated Litespeed after the update it was working, but after sometimes showing the same error., still facing this.
