I have updated my Check_MK to v126.96.36.199p12. Almost everything is working fine except the LDAP login. I am getting the message repeately:
[Wed Oct 13 15:45:16.747766 2021] [wsgi:error] [pid 367] [client 127.0.0.1:44232] WARNING: yacc table file version is out of date, referer: http://myserver/sitename/check_mk/login.py
Google said that it is related with pycparser package. However, after I uninstall and reinstall the package, the problem is still there.
It would be appreciated if you could help me fix the problem.
Thanks and regards,
