Internal Server Error when clicking Acknowledge Alert only for one group of hosts 🔗 link

If I am a layer up Acknowledge Alert works without giving any internal
server error.

Any suggestion on where to look?

Thanks

Hmm. Was not able to duplicate this on my side.

I would begin by setting XYMONCGILOGDIR in your environment to somewhere apache (etc.) has write privileges, then adding --debug to CGI_ACK_OPTS in cgioptions.cfg. That should result in logs there. Alternatively, --debug=stderr should send at least the debug output over to your normal apache log.

HTH,
