Nagios Support Forum

I ran into a similar issue during an offline upgrade — the script looked successful, but the version didn't update in the frontend or xiversion file.

Ugh, “An error occurred. Please try again” is the worst! Okay, don’t panic, the key is finding those logs. Usually, Nagios logs are hiding in /var/log/nagios/, but if not, check your Nagios configuration file for the log_file directive – that’ll tell you exactly where to look!
