Hello,

Nagios XI is failing to apply configuration with the error:

Error: Template '' specified in host definition could not be not found (config file '/usr/local/nagios/etc/hosttemplates.cfg', starting on line 503)

It literally says Template '' (no name). Line 503 in /usr/local/nagios/etc/hosttemplates.cfg is the end of the file.

I've checked all of our host definitions, and they're are all using templates that exist. I've also tried deleting and re-writing the config files from the GUI - no luck.

Any ideas?

Possibly relevant: we updated to Nagios XI 5.7.4 (from 5.6.7) last week.

Can you please get and upload a system profile zip by going to Admin => System Profile (in the left menu), then clicking the blue button, then PM-ing it to me?

System profile received. Investigating now.

If you go into Core Config Manager (CCM) and mark the Host Template called "xiwizard_generic_host" as Active, it should resolve the problem.
